I don't question your experience.-I thought my extractor hook broke off which could have happened sometime after 5,000 rounds, but that's also normal from my experience with any brand.
Class went great. Pistol ran great. On the second day I had 2 malfunctions one of which was fixed with a simple tap rack. The other one I tap racked and a live round wedged itself into the ejection port. Had to rip the mag, lock the slide and hammer at it with my hand in the middle of the drill/scenario we were running.
Uncle Sugar drummed the tap-rack-bang malfunction drill into my head too.On the second day I had 2 malfunctions one of which was fixed with a simple tap rack.
Based only on this information, my first guess is the extractor has excessive deflection and/or too much tension. The common advice for fixing feeding problems caused by the extractor is to lessen the amount of tension on it. However, tension is only one part of the formula for making an extractor function 100%. It is very common for 1911 manufacturers to do a half-assed job fitting extractors. Go to this LINK for a look at what's involved with correct extractor fitting.One of them that's definitely what happened. The other may have been the same, but I can't be sure.
Same here.Tap rack is so drilled into me I instinctively did it.
A weak recoil spring is less able to resist the rearward movement of the slide so it wouldn't cause the slide to stop short of going fully to the rear.I don't know if the slide didn't come back far enough to fully cock the hammer? Still the original recoil spring in the gun after almost 10 years so it's probably due for a replacement.
All the ammo was 230gr FMJ from Fiocchi.
After that last post I took it apart to clean it and the wilson combat shok-buff had actually split almost in half so now I'm thinking that was the culprit.
Or maybe it was just getting dirty and muddy and having trouble from that. Was drizzling and muddy most of the second day.
Okay, it's not the fault of the ammo.All the ammo was 230gr FMJ from Fiocchi.
Bingo. I agree with @TunnelRat that shok-buffs don't belong in a self-defense 1911. Also, as he says, feel free to use one in a range toy but realize that the buff reduces the distance the slide can move rearward. This can result in short stroking of the slide leading to bolt-over-base malfunctions. This is especially true in shorter than 5" pistols. Chunks of your destroyed buff probably gathered in front of what was remaining of the buff and effectively made it thicker resulting in the slide not moving far enough to the rear to allow it to pick up the next round out of the mag cleanly.After that last post I took it apart to clean it and the wilson combat shok-buff had actually split almost in half so now I'm thinking that was the culprit.
As long as it's kept well oiled incidental rain and mud exposure shouldn't cause it any problems.Or maybe it was just getting dirty and muddy and having trouble from that. Was drizzling and muddy most of the second day.
