Some of you may have heard of the Bullite system that is a laster cartridge that fits in your barrel and when you fire the trigger it contacts the rubber pad on the bullite cartridge and fires a laser beam out of the barrel. This allows you do try fire with special targets and such. Well I have a 9mm bullite and have been using it in my XD and Glock 9mm but it won't work in the M&P 9mm. I'm not sure why or if the cartridge sits too far for ward or the firing pin just doesn't make it to it? If anyone has any ideas? Just thought I'd pass that along for those of you that were contemplating that system for use in your M&P as it might not work.
