We don't have much firearm talk but I was wondering if anyone has used the TLR-4 laser / flashlight. I'm thinking of getting one for my Springfield XD-40. The TLR-3 was my first choice but TLR-4 is newer model and half the cost. It should also fit my Colt CC 45 so that's a bonus. This is a nightstand (not literally) gun for home protection so I like the compact design and I don't need it in a holster. Any users out there?
