I've done a lot of cold weather shooting (MN) and never had any trouble with any handgun as far as reliability goes.
I'm much more concerned about how the gun handles with numb, stinging fingers or with gloves on.
Some revolvers will pinch your gloves between the frame and trigger, preventing the trigger from reseting. That happened many times to me with K frame Smiths.
My cherished Freedom Arms 97 has such a light trigger that it's hard to shoot safely with numb fingers. The trigger guard is also very small.
I've found 1911s, USPs and Glocks to be the easiest guns to load and fire effectively in bitterly cold weather.
