A 45-gauge semi-automatic handgun! Hmm, I wonder what a 45-gauge works out to be in caliber? At least it's somewhat better that the Atlanta MSM types in the wake of the Brian Nichols rampage, who described his captured Glock-22 as a 40 mm. handgun!! I can't even imagine the recoil would be on a 40mm Glock - a real hand cannon! Those cartridges must cost 5 dollars each. Oy!
I'm thinking its a Colt 45.
