Crimson trace on s&w 638 .38+p - Crimson Trace Smith and Wesson J-Frame Revolver Round Butt Lasergrip Green Laser Sight

This laser grip from Crimson Trace is a direct replacement for the factory grips on the Smith & Wesson 638 (and other J frames per their description). An easy swap with jus one screw. The CT grip is a bit longer than the factory grips which is nice if you have larger hands. The green laser is very bright and works well in the daylight at distances you would expect to shoot a snub nose .38. It runs on four lithium disk batteries that only cost about $1 a piece so replacing them won’t be too expensive. The laser is activated by pressing a button on the front of the grip with your middle finger. Very intuitive, almost automatic. It also has an on/off switch in the butt of the grip. The laser is situated in the right side of the grip. I was worried about obstructing it when shooting right handed. It is high enough in the grip that this has not been an issue for me. Easy to adjust the laser with the included Allen wrench.
