The hammer block needs to move freely to work properly. It is the only part in the Smith revolvers that does moves enough to rattle.
I just opened the box of a new Performance Center 327, 2" barrel, and the rattle is tremendous, to the point that I initially thought there was a lose screw or something inside the wood grip. Despite having read many here say "it's normal", I still cannot fathom how S&W ships, by design, an expensive gun like this making this sort of noise. I must say I am actually kind of upset. I find the noise mind boggling. Literally, it sounds like a left-over screw inside the wood grip cavity. The noise is not faint at all. I also have a 5" Performance Center 327, and after this experience I shook it and noticed that it too rattles pretty good. But it is not as noise as the 2" one. You might as well attach a little bell to the bottom of the grip.

You should not own a gun that rattles! There is something drastically amiss and you should package it up immediately and send it to me. Because I don't want to see you suffer too long i am even willing to send you $100 Cash American Dollars to help you out. Just funnin' ya!
Like the other fellas said, it's the hammer block & perfectly normal. Only worry when it stops rattling.......
Welcome to the Forum!
So, has anyone else with one of these, or any S&W revolver, noticed a good rattle in the works?
