SAMMI pressure rounds only. No +P or +P+.

In your experience what is the round count life expectancy of a P7M8 (that will be fired no more than 200 rounds per range session) BEFORE a part failure that would put the gun out of action?

What part or parts are most likely to fail?

I am not counting extractors since the gun has a fluted chamber or replacing recoil springs.

Also, normal cleaning/lubrication after each range session would occur.

Hello rmc;

"IME"...indefinite life expectancy.

My original, now 34 year old P7M8, purchased NIB, which has fired uncounted tens of thousands of factory FMJ and JHP rounds (no reloads), including +P and +P+, has never had any malfunction of any kind, nor had any parts either break or wear sufficiently to require replacement.

It's admittedly been cared for assiduously, with cleaning and inspection (including particular attention to the gas piston and gas piston chamber) after each firing session, but never "babied".

After about 15 years, I did start to replace the recoil spring and the magazine springs every few years, "just because".

I've heard, second hand, of the firing pin bushing breaking, but never actually seen it occur.

Thanks Sawbones
That's exactly the kind of feedback usage I was looking for.

My firing pin bushing broke after 10K or so rounds.

Fixed under warranty.
