Winter, Springfield XD-357 In the summer and in the backcountry I carry the USP. That pistol has been through stream crossings, torrential rain, heat, snow, and mud. I have never had a malfunction in that weapon. In the winter I put a premium on penetration and due to bulkier clothes I can carry a larger pistol, so my XD-357 Service Model is my carry in the winter. Does anyone else do something like this?
