Does anyone know if these laser grips: http://www.crimsontrace.com/Home/Pro...2/Default.aspx

will work with a S&W model 42 "lemon squeezer" or not? Even though I didn't see my gun model listed, it did list the centennial as a model these grips would fit.

I'm thinking that because they don't cover the back strap or interfere with the grip safety they should. But are there any other differences between a model 42 frame and a current production J-frame that would preclude these laser grips from fitting this gun?
