Best 9mm Suppressor: 7 Cans by Price and Decibels

Last updated: October 31, 2026

Short answer: No single 9mm suppressor wins everything. In the independent pistol tests we found, the Banish 9 posted the lowest muzzle reading of our cans at TBAC in 2025, the Mojave 9 in its long setup beat the Omega 9K at the muzzle in two separate labs, and the RXD910Ti beat the VOID-9 at TBAC in 2026. The Banish 9K is the tiny one at 2.7 ounces, and the Milkman is built for carbines. Prices run from $699 for the Banish 9K to $1,029 for the Mojave 9 and Mojave 45.

A 9mm can is the one most folks end up using the most. 9mm ammo is about as common as it gets, and one can will ride on your pistol on Saturday and your carbine on Sunday. The trouble is that a 9mm suppressor sounds different on every gun you put it on, and the decibel claims don’t tell you which gun the maker used. So we lined up seven cans we list, took the specs from each maker and gathered sound data from testers who ran a lot of cans on the same gun with the same ammo. Every number below comes with its gun, its ammo and its microphone spot, and we don’t average them or mix numbers from different tests.

The seven cans and how we picked them

We stuck to 9mm and multi-caliber pistol cans available to order on our site as of October 31, 2026, and picked across the price range: the Banish 9K, the Canik VOID-9, the Banish 9, the Dead Air RXD910Ti, the Otter Creek Labs Milkman, the Dead Air Mojave 9 and the Dead Air Mojave 45. The SilencerCo Omega 9K gets a head-to-head section with the Mojave 9 because it’s the matchup folks ask about most, even though it isn’t available to order on our site as we write this.

You have to be 21 to buy a suppressor from a dealer, the same as a handgun (18 U.S.C. 922(b)(1)). The rest of the buying process changed this year, so our guide to buying a suppressor walks through it as it stands today. If you’re shopping for a rifle can too, our .30 cal comparison and our .22 suppressor comparison work the same way.

Price tiers, as of October 31, 2026

These are the prices on our product pages the day we wrote this. Prices move, so check the listing before you lean on any of this.

Under $850. The Banish 9K is $699 in 1/2×28 FDE and $699.99 in the 13.5×1 left-hand version. The Canik VOID-9 is $809.99.

About $900 to $950. The Banish 9 is $899, the Dead Air RXD910Ti is $929 in black or FDE, and the Otter Creek Labs Milkman is $950.

About $1,000 and up. The Dead Air Mojave 9 and the Dead Air Mojave 45 are both $1,029.

9mm suppressor comparison: the specs

Here’s how each maker lists them. Otter Creek Labs’ site wouldn’t load for us, so the Milkman‘s numbers come from Silencer Shop’s listing. Banish has renamed both of its cans since we listed them, and the table notes the new names.

The spread is wide. The Banish 9K is 4.1 inches and 2.7 ounces, and the Mojave 45 runs up to 8.6 inches and 12.7 ounces long. Most of the group sits between 6 and 7.7 inches. The Milkman is the oddball at 2 inches across the front, and it’s the only one here that uses a HUB thread and ships without a mount.

Look at how each can mounts before you look at anything else. The VOID-9, Banish 9, RXD910Ti and Mojave 9 come with a 1/2×28 piston for a tilting-barrel pistol. The Mojave 45’s piston is .578-28, the common .45 ACP thread, so a 9mm pistol needs a different piston from Dead Air. The Banish 9K is direct thread with no piston, and the Milkman needs a mount you buy separately. Our suppressor mounts explainer covers pistons, direct thread and the rest.

What the decibel numbers actually say

Start with the maker claims, which don’t line up. Banish says the 9 knocks off 34 dB (Banish), and the 9K knocks off 26 dB and reads 132 dB at the ear (Banish). SilencerCo lists a 135.8 dB muzzle average for the Omega 9K (SilencerCo). Dead Air’s RXD910Ti manual lists 134 dB at the muzzle and 132 at the ear on a 4.7-inch Ruger RXM with Hornady Subsonic, measured to MIL-STD-1474E (Dead Air). Canik and Dead Air don’t publish numbers for the VOID-9 or the Mojaves. Some of those are a reduction and some are a reading, all on different guns.

The numbers you can line up come from tests that ran many cans on one setup. Thunder Beast Arms’ Silencer Summit runs every entered can through the same guns and microphones at its indoor range in Cheyenne, Wyoming, and publishes the whole table. TBAC makes suppressors too, but its own cans sit in the same tables as everybody else’s. Since 2024, its standard 9mm host has been a Canik METE SFX pistol shooting Ammo Inc Stelth 165 gr. PEW Science runs its tests on an HK P30L with Speer Lawman 147 gr. Only compare rows below that share a source, host, ammo and test date.

A couple of things to read this table right. TBAC’s muzzle number averages two microphones 1 meter left and right of the muzzle; its 2023 tables only had the left one. The ear number is the shooter’s ear. PEW’s Suppression Rating isn’t decibels at all. It weighs the shape and duration of the sound along with the peak, and higher is quieter.

The 2025 summit put five of our cans on the same Canik. At the muzzle, the Banish 9 read 121.9 dBA, the lowest of our group, followed by the Mojave 45 long at 130.0 and the Omega 9K at 133.2. At the shooter’s ear, the order shuffled. The Omega 9K read 128.10, the Mojave 45 long 130.14 and the Banish 9 130.53 (TBAC 2025 results). In 2026, the RXD910Ti read 129.1 at the muzzle and 129.51 at the ear, against 135.5 and 130.43 for the VOID-9 (TBAC 2026 results). In 2024, the Mojave 9 long read 127.2 and 130.57, and the same pistol with no can read 158.7 and 153.01 (TBAC 2024 results).

Notice how tight the ear numbers are next to the muzzle numbers. In 2025, the five cans from our list spread about 15 dB at the muzzle and only about 4 dB at the ear. A can only quiets what comes out the front. On a pistol, some of what you hear comes out of the gun’s action, near your face, and no can fixes all of that.

The Milkman row needs a footnote. TBAC tested it on the pistol, but Silencer Shop’s listing says pistol use with a booster isn’t recommended and voids the warranty (Silencer Shop). That makes the row useful as a comparison and not as a recommendation to run it that way.

Why the host matters so much on a 9mm

The same can will meter differently on every 9mm you own, and the ear number moves more than the muzzle number. TBAC’s 2023 tables show it plainly. The same Mojave 9 with the same Blazer 124 gr read 126.33 dBA at the muzzle on an MP5K and 126.25 on a CZ Scorpion, nearly identical. At the shooter’s ear, it was 138.73 on the MP5K and 146.98 on the Scorpion (TBAC 2023 results). The can and the ammo were the same, so the 8 dB came from the gun.

Dead Air’s own RXD910Ti numbers point the same way. On the 4.7-inch Ruger RXM pistol, Dead Air lists 134 dB at the muzzle and 132 at the ear. On the 16.12-inch Ruger PC Carbine, it’s 127 at the muzzle and 135 at the ear (RXD910Ti manual). The carbine was quieter at the muzzle and louder at the ear, and on a carbine your face sits a lot closer to the action.

Pistols bring their own problem. PEW Science notes that almost all common combat handguns use a modified Browning tilting-barrel action, which doesn’t get along with back pressure. Blowback, gas and grit coming back out of the action, is relatively common on suppressed centerfire handguns (PEW Science, PEW Omega review). Those same tilting barrels are why pistol cans ship with a booster, or piston, which lets the barrel move so the gun cycles with a can on it.

Ammo matters too, and TBAC’s 2023 MP5K test shows what a heavier bullet does. Switching the Mojave 9 from Blazer 124 gr to Stelth 165 gr dropped it from 126.33 to 120.34 dBA at the muzzle and from 138.73 to 134.15 at the ear. The Omega 9K moved far less on the same switch, from 138.13 to 136.92 at the muzzle.

Banish 9K: the tiny one

At $699, the Banish 9K is the least expensive can here, and it’s by far the smallest at 4.1 inches long, 1.3 inches across and 2.7 ounces. It’s printed titanium, and Banish sells it in 1/2×28 or 13.5×1 left-hand direct thread with no piston needed. Banish rates it for .380, 5.7×28, 9mm and .300 BLK, with full-auto use on 9mm supersonic and .300 BLK subsonic (Banish). Banish’s site now calls it the TAC 9K TI.

Small has a cost. In TBAC’s 2025 pistol test it read 137.2 dBA at the muzzle and 132.12 at the ear, the loudest muzzle number of our five cans in that event. It made up ground at the ear, where it trailed the Omega 9K by about 4 dB. For a pistol you carry or a can that keeps the gun short, it makes sense. For the quietest bench session, look further down this list.

Canik VOID-9 vs Dead Air RXD910Ti

These two landed in the same 2026 TBAC table on the same Canik, so they’re the fairest pairing in the group. The Canik VOID-9 is Canik’s own can, 6 inches long, 1.375 inches across and 7.5 ounces of Grade 5 printed titanium with a Cerakote finish. It ships with a 1/2×28 piston and both a solid and a vented end cap, and the rear threads are 1.125×28, so it’ll take mounts built for that pattern. Canik lists no barrel limit on 9mm or subsonic .300 BLK and .338 ARC, a 9-inch minimum and semi-auto only on supersonic loads, and .357 Mag on lever-action rifles of at least 8 inches (Canik).

The Dead Air RXD910Ti comes from Dead Air’s line with Ruger. It’s 7.7 inches, 1.48 inches across and 11.4 ounces of 6Al4V titanium with Dead Air’s Triskelion baffles, and it ships with the PB440 1/2-28 piston. Dead Air bores it for 10mm and rates it from 5.7×28 through 9mm, 10mm, .357 Mag, .300 BLK and 400 Legend, full-auto on 9mm, 10mm, 5.7×28 and subsonic .300 BLK, with no barrel restrictions (Dead Air).

On the 2026 Canik, the RXD910Ti read 129.1 dBA at the muzzle and 129.51 at the ear, and the VOID-9 read 135.5 and 130.43. That’s a clear muzzle win for the RXD and a near tie at the ear. The VOID-9 is 1.7 inches shorter and nearly 4 ounces lighter by the makers’ numbers, and it’s about $120 less on our site. If you also run 10mm, the RXD is the one rated for it.

Banish 9: the quiet one at the muzzle

The Banish 9 posted the lowest muzzle number of the cans we list in TBAC’s 2025 pistol table, 121.9 dBA on the Canik, with 130.53 at the ear. It’s 6.8 inches and 6.73 ounces bare, or 7.16 inches and 8.57 ounces with the 1/2×28 Micro Booster it ships with, 1.35 inches across. It’s titanium with a 7075 aluminum tube and front cap, user-serviceable with 14 baffles, and the caliber list is the longest here, from 5.7×28 and .32 up through .357 Mag, .300 BLK and .350 Legend (Banish). Swap the booster for a direct-thread mount and Banish says it’ll run on a pistol caliber carbine or lever gun at 6.8 inches. Banish now sells it as the PSTL 9 TI and calls it the quietest 9mm suppressor on the market. That’s their claim. TBAC’s 2025 table backs it at the muzzle among our cans, though not at the ear.

It does well on a rifle too. In TBAC’s 2025 test on a 16-inch .300 BLK bolt gun with subsonic Stelth 220 gr, it read 128.1 at the muzzle and 125.27 at the ear. If 300 Blackout is part of the plan, our 300 Blackout suppressed guide goes deeper.

Otter Creek Labs Milkman: the PCC can

The Otter Creek Labs Milkman is built for carbines and subguns, not pistols. It’s 6 inches long, 2 inches across the front tapering to 1.5 at the rear and 8.8 ounces of DMLS Grade 5 titanium. It’s full-auto rated on 9mm with no barrel length limit, and it uses a HUB 1.375×24 rear thread with no mount in the box, so budget for one (Silencer Shop). Silencer Shop’s listing also says pistol use with a booster isn’t recommended and voids the warranty.

TBAC tested it anyway. On the 2025 Canik, as entered at 16.5 ounces, it read 135.5 dBA at the muzzle and 131.14 at the ear. In 2026 on the subsonic .300 BLK bolt gun, it read 139.0 and 130.56, though our source lists only 9mm, so check with OCL before you go that route. We didn’t find an independent PCC test with the Milkman on it, which is a gap if a carbine is your main gun.

Mojave 9 vs Omega 9K

This is the one we hear about most, and it’s one of the few 9mm matchups with clean data from two independent testers. The Dead Air Mojave 9 is a modular can that runs 5.89 inches and 8.2 ounces short or 7.64 inches and 9.6 ounces long, 1.405 inches across. It’s 6AL-4V DMLS titanium with 7075 aluminum and stainless parts, ships with a 1/2-28 piston, takes Dead Air’s P-Series adapters and is rated full-auto on 9mm and subsonic .300 BLK with no barrel restrictions (Dead Air).

The SilencerCo Omega 9K is shorter and fixed-length, 4.54 inches, 1.48 inches across and 7.3 ounces of Cobalt-6 and 17-4 stainless, with no tube. It mounts on SilencerCo’s Alpha pattern, which takes a piston, direct thread or 3-lug. SilencerCo rates it for 9mm and .300 BLK with a 7-inch minimum barrel on .300 BLK, and lists that 135.8 dB muzzle average (SilencerCo). It isn’t available to order on our site as we write this.

TBAC 2023, same MP5K, same ammo. With Blazer 124 gr, the Mojave 9 long read 126.33 dBA at the muzzle and 138.73 at the ear, and the Omega 9K read 138.13 and 137.60. With Stelth 165 gr, the Mojave read 120.34 and 134.15, and the Omega 136.92 and 137.69 (TBAC 2023 results). The Mojave led at the muzzle with both loads, by 11.8 dB with Blazer and 16.58 with Stelth. At the ear, the Omega was about a decibel quieter with Blazer, and the Mojave was about 3.5 quieter with Stelth. Keep in mind the Mojave was in its long setup here, about 2.7 to 2.9 inches longer than the Omega as TBAC measured them.

PEW Science, same P30L, same ammo. PEW rated the Mojave 9 long at 58.3 and short at 48.8, and the Omega 9K at 43.6 (Mojave 9 review, Omega 9K review). PEW says the Mojave in its short setup matches the muzzle suppression of the shorter Omega 9K and “significantly outperforms the higher back pressure Omega 9K in operator hazard reduction.” PEW tested the Omega with a HUXWRX piston, and it cautions that third-party pistons in the Mojave may hurt its performance, so stick with Dead Air’s.

The two cans also sit in different TBAC years on the Canik pistol. The Omega 9K read 133.2 and 128.10 in 2025, and the Mojave 9 long read 127.2 and 130.57 in 2024. Same gun and ammo, but different events, so we won’t call that one.

Our read: if quiet is the goal and a couple of extra inches don’t bother you, the Mojave 9 has the better independent record. The Omega 9K is shorter and lighter, and it edged the Mojave at the ear with Blazer on the MP5K. PEW also flags first-round pop on the Mojave 9, the louder first shot through a cold can, at the muzzle, saying it may be more than 30 percent more severe than on the Rugged Obsidian 9.

Dead Air Mojave 45: one can for 9mm and .45

The Dead Air Mojave 45 is the bigger sibling, 1.48 inches across, 6.812 inches short or 8.6 inches long, and 10.44 to 12.7 ounces depending on setup. Dead Air rates it full-auto on pistol calibers up to .45 Auto with no barrel restrictions, plus subsonic .300 BLK full-auto on an 8-inch barrel and a list of rifle loads semi-auto (Dead Air). It ships with a .578-28 piston, so plan on a 1/2×28 piston from Dead Air if it’s going on a 9mm pistol.

On TBAC’s 2025 Canik, the long setup read 130.0 dBA at the muzzle and 130.14 at the ear, ahead of the Omega 9K at the muzzle in that same table. Short, it read 137.1 and 131.35. If you shoot both 9mm and .45 ACP, it’s one can for both.

Also worth a look: YHM Sidewinder M2

The 9mm Sidewinder M2 beat the Mojave 9 long at both spots in TBAC’s 2024 pistol table, 122.8 dBA at the muzzle and 128.55 at the ear on the Canik, against 127.2 and 130.57 (TBAC 2024 results). YHM lists it at 8.2 to 8.35 inches and 8.8 to 10.2 ounces, in aluminum and stainless with a 1/2-28 piston (YHM). It isn’t available to order on our site as we write this. The .45 ACP version is $569 on our site, but TBAC tested the 9mm one, so those numbers don’t carry over (YHM .45 page).

Which one we’d put on which gun

For a quiet pistol can, the Banish 9 had the lowest muzzle number of our cans at TBAC in 2025, and the Mojave 9 long has strong numbers from two labs. If you want something shorter and lighter, the Banish 9K is the one to carry. For a fair budget comparison, the RXD910Ti beat the VOID-9 at the muzzle in the same 2026 test, and the VOID-9 is shorter, lighter and less money. For a carbine or subgun, the Milkman is the one built for it. And if a .45 is in the safe, the Mojave 45 covers both.

You’ll find all of these and the rest of the lineup in our silencers section. If this is your first can, start with our guide to buying a suppressor.

FAQ

What is the best 9mm suppressor?

There isn’t one winner. In TBAC’s 2025 pistol test, the Banish 9 posted the lowest muzzle number of the cans we list, and the Omega 9K posted the lowest at the shooter’s ear. In 2026, the Dead Air RXD910Ti beat the VOID-9 at both spots. PEW Science rated the Dead Air Mojave 9 long at 58.3. Pick the test that matches the gun you’ll shoot.

Is a 9mm suppressor quieter on a pistol or a PCC?

Usually quieter at the muzzle on a carbine, but not always at your ear. Dead Air’s RXD910Ti manual lists 134 dB at the muzzle and 132 at the ear on a Ruger RXM pistol, and 127 at the muzzle and 135 at the ear on a Ruger PC Carbine (Dead Air). Even between two subguns, TBAC’s 2023 tests had the same Mojave 9 and ammo about 8 dB apart at the ear.

What ammo is quietest in a 9mm suppressor?

Heavy bullets are what the testers use. TBAC runs Ammo Inc Stelth 165 gr, and PEW runs Speer Lawman 147 gr. In TBAC’s 2023 MP5K test, switching from 124 gr Blazer to Stelth dropped the Mojave 9 from 126.33 to 120.34 dBA at the muzzle and from 138.73 to 134.15 at the ear.

Do I need a booster to suppress my Glock?

Most likely. A Glock, like most centerfire pistols, uses a tilting barrel that has to move to cycle, and the booster, or piston, keeps it running with weight hanging off the end. The VOID-9, Banish 9, RXD910Ti and Mojave 9 all ship with one. The Banish 9K is the exception here; at 2.7 ounces, Banish says it runs without a piston. Most Glocks also need a threaded barrel first.

How loud is an unsuppressed 9mm pistol?

In TBAC’s 2024 test, a Canik METE SFX with Ammo Inc Stelth 165 gr and no can read 158.7 dBA at the muzzle and 153.01 at the shooter’s ear (TBAC). With a Mojave 9 long on the same pistol and ammo, it read 127.2 and 130.57.

How old do you have to be to buy a 9mm suppressor?

You have to be 21 to buy one from a dealer, the same as a handgun (18 U.S.C. 922(b)(1)). The rest of the process changed this year, and our guide to buying a suppressor walks through it.
