Works great for a j-frame air wieght s&w hammerless revolver - Crimson Trace Smith and Wesson J-Frame Revolver Round Butt Lasergrip Green Laser Sight

One of the biggest issues with a stub nose hammerless 38 is that you basically need to be on top of the target before you can hit the broad side of a barn. Enter the only time I've ever found a Crimson Trace laser to be 100% valuable. The laser grip is an excellent replacement for an OEM SW 38 Air Weight 642 revolver. The GREEN laser is very bright and gives you the ability to aim in the center of mass. (Which with a 38 stub nose is the only place you have any chance of hitting.) This sight changes the ability to use the revolver from a "I might be able to hit a very close target) to a "I can hit a target out to 3 yards reliably." Huge difference that technology can actually help you solve. This doesn't change the revolver type for being used only in a critical emergency, that's still the case. However, it increases the safety margin for use significantly.
