I remember recently reading on FN Forum about several folks who thought they had cracked frames but it turned out to be "mold marks". There was a problem more than a year ago with a few with faulty fire control housings that cracked but far as I know, that's been taken care of. Haven't heard anything else about FNP cracked frames & I have 2. 3000+rds thru one and 2000+ thru other.

If it really is cracked and not anything like what forestranger noted it is some way out fluke of a situation. There are way too many of those weapons out there with many-many rounds put through them to see it as a big problem. I've not heard much of anything bad about the FNP's since they come out. I don't think it's enough to see the weapons as unreliable. But if your friend can't trust his anymore hew should get rid of it. A weapon you cannot trust 100% is useless to you.

I totally agree...
