I'm new at this and have been watching you tube videos fast and furious trying to learn. I just started with a Gamo Swarm Maxxim and I may never get beyond that. But maybe will, who knows. Whichever more knowledge is a good thing. But I realize that not all YT info is good info but I did see something about hammer bounce that seemed to make sense.......that lack of it can extend, or stop the waste of, air tank supply. I've been looking at specific gun info, including those you mentioned, but couldn't find any mention of floating hammers. Thus, my question.
While I said I may never get beyond my present gun, I have found two local dive shops (LOL).
