In the days before YouTube university I bought an M1A. The owners manual was filled with dire warnings about what would happen if you took apart the gas system with the wrong tools or in the wrong manner. Being a young broke Sheriffs Deputy it took me a year to save for the gun so I sure didn't want to break it. I looked for a maintenance course and couldn't find one. I called them up and asked. No such offerings. I told them I was a local officer and asked if I stopped by, could they show me. Nope. Years later I placed a Department order for 6 1911's and one was for our left handed Sheriff. They offered a ambi mag release and the gun was ordered with one. When it got close to delivery time I emailed Lexi, their LE contact, and she confirmed the mod. The Sheriff,s gun arrived without it and back it went. When it returned the Sheriff noted it was hitting way left. Me and another RO confirmed it and inspection of the sights revealed the rear was not centered, or even close. We couldn't get it to budge. Something was oversized or undersized and they sent it out. Back it went. Massad Ayood wrote a glowing article about the loaded 9mm and I bought one. 18 FTE's out of the first two mags. Slide movement felt like sand in the rails and no amount of cleaning would get rid of the grit. I believe they used lapping compound to fit the slide to frame and abrasive got embedded in the steel. Shot different brands of ammo, different spring weights. Worked through 500 rounds, hand cycled it two hundred times. Nothing helped. This was a early gun with a non ramped barrel. I also did not know anything about extractor tension. Sent it back and it still wouldn't run. Sold it at a loss and haven't bought a Springer since. 38 Super baby! 3 guns from 3 companies, 0 malfunctions. I have been tempted many times (most recently by the Ronin) but can't get past my experiences of 15-20 years ago. Sounds like not much has changed.
