As you can see at a discussion below, I bought a magazine for my M9-1A that was rusted. Cleaned and lubed the magazine and took it out to the range today. First loaded 5 rounds, fired, no problems. Next loaded another 5 rounds, fired, like buttah! Next loaded another 5 rounds and pulled the trigger. Wish I had a camera recording it!!!! That one pull sent 2 rounds down the barrel, and loaded the next round in the chamber. That's right, folks! The puppy went auto on me! I figured it was the magazine, so I stopped using it and fired about another 100 rounds with other magazines, just fine. Not a single failure rest of the day. This is kinda funny, cause the range master guy told me back in december that the M9-1A he had, kept firing 2 rounds at a time, too. He sent it in to SAI, they kept it for a while and told him that they couldn't figure out why and returned him a M40-1A instead. Anybody else had their gun go auto on them? I was honestly surprised that my gun actually extracted both rounds, knowing how finicky it is just extracting one at a time.
