Is this a recent thing? Temperature drop means gas efficency will be down and once it gets down to single digits a lot of pistols will be next to useless. Simple answer is something Tokyo marui they have the best design/quality control and being mainly plastic they are much more gas efficient than the metal clones. If you want a 1911 the M45A1 is the most recent TM design and has very good efficiency for a single stack. I personal rate the HK45 Tactical. It's a double stack mag so large gas capacity. Grip is adjustable depending on hand size, controls are ambi, comes with a threaded barrel so can fit a pistol tracer. If you want to go cheap the AAP-01 is really good value for money and has massive after market support. They do gave a reputation for breaking though.
