I got a .45 caliber LaserLyte cartridge for Christmas - the little brass cartridge that slips into the chamber and blasts a momentary red dot on the wall, hopefully somewhere close to the actual point of impact, when the rear of the cartridge is struck by the firing pin. Now I didn't really expect it to work. There's just too much variance in chamber dimensions. But, you know, the LaserLyte was a gift and all, and the giver meant well. The thing is, it almost works. It just goes about .005", or maybe .010", too far into the chamber after the first firing pin strike. The pin can't hit it a second time. So I thought I'd ask if any of you smart guys have a solution for either spacing it back from the front of the chamber or closing the gap at the rear. Any ideas? Thanks.
