Years ago I did an article where I took my carry gun, at the time a Glock 19, out to the range on a frigid day in November, and tested my performance on the graduation exercises from the Intensive Handgun Skills speed shooting course from InSights Training Center, using bare hands, thin gloves, and heavy gloves. I found that even thin gloves reduced my shooting performance by 40 percent versus bare hands. Thank you, no. This reinforced to me that my choice, in winter, to walk around with my bare hands in my jacket pockets, keeping them warm and supple and ready, and a pair of gloves in other jacket pockets, to be put on only if I needed to expose my hands to cold for an extended period, was the right one.
