Fortunately, a LOT smoother than might be thought with all the linkage. Remember the "hammer" doesn't strike the firing pin, it's also done thru a linkage. The "hammer" is merely a cocking piece for single-action firing. I've not had to work on one yet, and they do come with a lifetime guarantee(thank you) and because of being a rather strange looking beast (like it's namesake) it will remain a niche item in the market. They don't sell a lot of them, but they do sell steady on a yearly basis. Just think, if Sam Colt had come up with the idea of firing the lowest chamber, ALL revolvers might look like this, until some "oddball thinker" like Bill Ruger came up with the RedHawk !
