welcome to the forum. The LaserMax should fit....I cannot imagine the frame being any different than the .357 or 9mm. Might be a good idea to call the company to confirm before spending big bucks, however. She's gonna love that gun if the trigger is even close to being as good as my 9mm trigger. I have always been a J frame guy, but you'll have to spend some money on a trigger job on the J frame to match the LCR trigger. Good luck and keep us posted.
