I bought an 8mm blank firing (non-gun) M1911 off of Ebay. It is not only great for training, but great for scaring the crap out of would-be toughguys trying to rough you up.
My brother bought the same blank firing (non-gun) off of Ebay, except he got a Glock model. We just use the old Attacker-Defender scenario, when one has his weapon out, and the other doesnt. It improves draw times and manuevers greatly.
I use my bathroom mirror for stare downs with the blank peice, and a full length to check my prone sniping form with my M44 rifle.
