Another winner from crimson trace! - Crimson Trace Laser Grip with Rubber Over Mold for Smith & Wesson J-Frame Pistol

This compact laser grip considerably enhances the concealability of your J-Frame, especially for pocket carry, all while providing the advantage of a putting a laser on target!
While obviously a small grip like this cannot provide the level of control and ease of handling of a full-size grip, it is surprisingly effective given it's diminished dimensions and deep concealability.
Crimson Trace Laser Grips are expensive but you get what you pay for... I have a CT grip in service I bought way back in 2005 (20 years ago!).
It's still working great!
