The award-winning G-Series laser sights provide an even more compact frame application than traditional Lasergrips, compatible with your subcompact sized GLOCK’s lightweight configuration. Engineered with Crimson Trace’s “instinctive activation”, the laser sight is engaged from the rear with your natural firing grip. Crimson Trace G-Series Lasergrips have been recognized with two Golden Bullseye Awards from the National Rifle Association and a High-Tech Product of the Year Award from the Firearms Industry Academy of Excellence. No other laser sight has won more awards. Lasergrips fit Glock 29 and 30, does not fit SF Models.
