I have owned this pistol for a year or so and last winter I decided to bring it deer hunting. Living in Western NY it gets cold and on a particularly cold day when I went to shoot it at a deer the firing hammer dropped but no discharge. I checked to make sure there wasn't grease on the pin and cleaned/lubed it. I finally got around to testing it under smilar conditions by sticking it in the freezer and same thing happened, no discharge. Any ideas?
