I have a new Special Combat Government 45 and it is beautifully finished and functions more reliably than any other pistol I've owned. This thing feeds, fires, and ejects everything. I would trust this pistol to operate any time with any ammunition. The only thing is accuracy. It came with a 15-yard test target that was a ragged hole with one flier that made it about a 1.5-inch group. The target stated 185 grain JSW. I have not been able to duplicate this target, but I am using 200-grain lead and jacketed SWC. The best I can do is 2.5 to 3-inches at 15 yards and this is consistant over a wide range of loads, and it's not getting any better after 1000 rounds. My other 1911 Colt pistol, an old model 70, makes one hole at 15-yards. I admit I am using light target loads. Does anyone know where Colt's test ammunition comes from or what is their test load? I may try their load before sending the gun back.
