^^^Not everyone takes pictures all the time. I've picked a shaved piece of a 357 jacket out of my arm before (actually a couple of pieces). It happened, but I don't have pics.
If you want a PWS, then buy one.
Agreed. We're all conditioned to immediately say, "Pics or it didn't happen," but pics aren't always available. I've seen a lot of things about OGC on a lot of threads, but none of it substantiated in any meaningful way, and I've never heard somebody call them dishonest, or anything of the sort. If OGC says he saw one blow up in the manner described, I believe him.
I also wouldn't let it color my opinion of a particular firearm. If nobody ever bought a make/model of firearm that had suffered a catastrophic failure, there'd be no gun companies left. If you look around the dark recesses of the internet, you'll find stories and pictures of all kinds of guns coming unglued and injuring people, but that's not the norm, even for bottom of the barrel guns. (Can't wait for KingKeoni's Hi-Point review!

) Any gun may come apart at any time, for a variety of reasons, but the odds of it happening to you are statistically insignificant and not worth worrying about. Much more germane in terms of "quality" is how well the gun works. Does it cycle reliably with a wide range of ammo brands? Does it feel good ergonomically? Is it too heavy, or too light? All those things you can find a plethora of information on. It's much harder to find info on operating rods blowing up recievers and putting out eyeballs, because it basically never happens, with any gun, without a damn good reason. (i.e. I used it for a muzzle-down walking stick while hiking ten miles in to my hunting stand, then immediately took a shot at a bull moose. Derp!)
TLDR: If a PWS fits you well, feels good, meets any coolness requirements you might have, and seems like it will function reliably, buy a PWS, and forget the worst-case horror stories.
