I got me a pair and they fit. They are very comfortable and like you said, you can feel the trigger with them. I will be using them. Thanks for the advice.
Not really as much for cold weather, but for general hand protection, classic leather-palmed fingerless cycling gloves could be a good option. The good, traditional cycling gloves come with a fairly sturdy leather pad in the palm that extends into the the thumb. Good for, say, heavy loads in a light revolver that really hammer the palm.
