When it comes to the 1911's out there, there is a big differrence between the brands. this is one area where you get what you pay for. several of the off brands do not fully heat treat the slide and frame, instead they only spot heat treat the stress points like the military did when the 1911 was a issued firearm. I would stay with Kimber, Springfield, Colt, S&W, H&K, if you want a top quality 1911.
