So I finally got a Mark 23 after years of comptemplating getting one and I'm stoked, but have a question. I have been reading and watching video reviews on it and a couple people said that their hammers broke from thumbing back the hammer manually for single action dry fire practice. They said it's designed to break away and that this would happen if you manually cocked it a lot. Well how much is a lot? I cocked it maybe 30-40 times when I was playing around a little with it the other night so I'd think it should be fine right? I mean it's supposed to be one of the most rugged and tested pistols ever right?! Any of you hear of this "issue"?
