By "exception", I meant 6,000 rounds without a crack; perhaps my fault for not making clear what I meant. I'm pretty sure few of these guns see such use.
I don't know think anyone knows how long these guns will last. Same for service life (10,000 rounds?), and same for the the percentage of cracked frames. You may have more in the way of facts on all this that I'm unaware of and your experience may be far greater than mine.
You are certainly influenced by getting a remarkable number of rounds from your gun without problem. My remarks are influenced by a cracked Colt Agent frame and a cracked S&W Model 38 frame, but there is no "hate" involved.
In my post, I only asked how you accurately kept up with the number of rounds fired. I wasn't expecting a tirade on alleged "alloy frame hate", if there is such a thing.
