Great pictures.

Once you start to photograph firearms and want them to look GOOD you realize it is not easy at all. The darker finishes like to go black with no detail, and it can be a real trick to control burned out highlights on the stainless ones. I can see that you used some indirect or 'bounced' and balanced light. I like your technique - it makes them look clean, smooth and enticing.
Sorry, I'm in the picture biz so I had to comment.
