Last Saturday I was shooting w/ friends in mild temps of about 20*. I was wearing light gloves and twice had the tip of a finger catch in the magwell of my Glock.
Gloves can be a real problem in the cold with revolvers, too. I'm surprised Ed-of-too-many-letters didn't mention that in his post about firearms training in Alaska, actually.
I conducted some cold-weather training for a concealed carry article I wrote years ago. I learned, like you, that Glocks are prone to malfunctions when I wear a heavy glove, as are revolvers. The first shot is usually fine, but then as the trigger comes forward the glove fabric/leather gets jammed between the trigger and the frame and turns your expensive & fancy-pants gun into a crummy club that is now welded to your hand.
After that experience I took to wearing light & tight gloves in the winter, with either a heavier pair of gloves or a pair of mittens over that. I used to wear Hatch gloves, but they became obscenely expensive in short order. I've found that "Mechanix" brand work gloves are a good, tight fit, and passably warm for brief cold exposure in what passes for winter in most of the Lower 48.
