Not meaning to insult anybody, but I wonder how many of the problems mentioned in this thread are problems other than "the gun". Magazines often cause the loading and FTF problems in guns, and junky feed ramps cause lots of the loading problems. I've got a lot of the guns mentioned in these posts, and they all seem to run fine and put lead downrange for me... even the "classic" junk guns... FEG's, Tanfoglio clones, etc. .
I buy most of my guns "used" and if I can, talk to the previous owner and listen to the problems they had. When I hear how they "tried to fix" some of the problems, I know exactly where to go to get it running correctly. Guns are mechanical devices, and when they fit correctly, they usually run correctly. I've found dozens of extractors incorrectly mounted, bent magazines, dinged feed ramps, etc. that were simple to fix and viola... I had a gun that ran flawlessly.
Working in a gun shop, it's easy to take a gun apart and look to see if there is a problem actually existing, or if the owner just doesn't know what's going on. Many times, they bring guns back in that haven't had enough rounds through them to "break them in"... and most of the time, I send them back out with a couple of boxes of ammo to "finish the job". About 80-85% of them come back and tell me the gun "is now working perfectly". The initial exam often shows up the dinged feed ramps and dinged up magazines... which, when polished with use or replaced, let the gun run correctly.
If they're actually broken, we send them back to the factory, who want to record the problems and fix their assembly processes or designs... but most of the problems aren't design problems... and anybody can screw up an assembly of "bin" parts for a particular piece of equipment.
I've got the Llama .380's, Tangfolio clones, S&W 39, EAA witness 10MM, and a host of others that were declared "junk" here, but run like a sewing machine when I'm shooting mine. Yes, they might have jammed up or had a problem, but rather than cursing it out and throwing it away, I fixed the problems and now they run fine.
The only real piece of junk I've ever had was a Zastava M-88 that I never could get to run correctly... and that was (I think) a warped frame problem, because I did hours worth of work on it, and never could get it to function... but it wasn't bought with high expectations. It was a cheap gun and didn't have a lot going for it out of the box. I've seen other M-88's that ran fine, I just happened to get the one that was junk. Maybe, it was just "my turn".
Seriously, I think any gun that isn't destroyed is fixable, and for the most part, the problems are simple to fix. Make sure it's put together correctly first, that the parts fit and are working (magazines), and that you've run enough ammo through it to clean out the "manufacturing flash" that's left in the rails and parts, and you'll find a world of difference. Most manufacturers recommend sending 200 rounds through the gun before sending it back to the factory (unless obvious flaws, like broken extractors occur), and then give it a good cleaning and make sure you shoot the type ammo the gun likes.
