Wow! I'd be interested in seeing pictures of what you find. I'm sure you'll be able to fix it. Most of the problems I've seen with pistols (semi-autos) have been due to poor ammo (Russian steel-cased garbage), poor internal springs, weak mag springs or poor quality after-market mags. A good cleaning, oil/grease and good ammo and mags have fixed every pistol I've worked on. I really enjoy getting these guns back into shape, it's very challenging and rewarding (not financially, though).

The Internet provides me with all the information I need to get up to speed quickly on a particular pistol and learn about it's mechanisms and common issues.
