FerFal wrote about winter carry recently. I have some thoughts and since work today could turn out to be completely rediculous I am writing this in advance.
I have spent a lot of time living in places with pretty cold winters. Not like -700 Minnesota kind of winters but lots of time between 5 and 20F not including wind chill with snow that stayed around for long periods. I also habitually carry a gun. Naturally for 3-4 months of the year the two sort of collide.
I find winter carry easier than summer carry. Concealing anything less than a pistol grip pump shotgun or a folding stock AK-47 is easy. For access it should go without saying that a pistol under a zipped and buttoned coat is about useless. Not as useless as say, a pistol in your nightstand but it's still not going to be a factor in a fight. I find that under most circumstances just keeping your jacket open works really well. It usually necessitates at least a mid weight type shirt or sweater under your coat if the temp is below about 30 degrees. Nothing crazy just something more than a t shirt.
The real decision point to me is if you are going to keep your coat on or take it off. If you are going to keep it on then an outside the waistband holster combined with an open coat is a super fast draw. A shoulder holster would work also. YMMV but I have found this good for when you will spend the majority of your time outside or are just going to one place and not staying that long. Great for a walk or a trip to the grocery store. The other situation is that you are going to be taking your coat off and then the 1911 on your hip might be an issue. In this case it is another layer which slows things.
Carrying in a coat pocket is a hotly debated issue. Revolvers are best with hammerless being most ideal. You really want to have a holster so you don't go to draw and come out with the barrel in your hand. Without a holster I have found one technique that seems to work. Just keep your hand on the grip. Assuming you have a pocket with a good opening (not one of those weird ones where the pocket is bigger than the opening and the edges are awkward) and your hand is already on the gun that is as FerFal says a very fast draw. Nobody notices a guy with his hand casually in a coat pocket. This is also convenient because you just stick a wheelgun in your pocket and go grab a quart of milk. However the downside is that while you could take your coat off you can't really leave it, or at least I wouldn't want to in almost every setting. So you might as well IMO just keep it on and carry under the coat.
I am interested in your thoughts and experiences on winter carry.
