I posted about this issue in the handguns forum, but had a more specific question so figured I'd ask you all here.
I pierced a primer in my S&W 29-8 and it torched the firing pin something ugly. I then fired another round and the destroyed firing pin stuck in the primer so that the gun was frozen up solid. It took quite a bit of work to get it freed.
The firing pin was perfect before, and burnt to a crisp after one pierced primer. Is this a fluke, or could it be blamed on the MIM firing pin. I know they say that S&W MIM (Metal Injection Molded) parts are supposed to be just as good a traditionally manufactured parts, but I had just never seen a part torched like this with one primer. It wasn't even a hot load, just a bad primer.
The reason I ask is that I'm getting ready to order a new firing pin, and I can get a replacement S&W MIM pin, or a machined aftermarket stainless steel one.
