I've noticed something about the 1911 and the Chip McCormick mags I feed it.
The won't feed properly everytime. Usually the first round in a mag, when it does fail. FMJ bullets.
Could it be a weak spring? Strong spring? Too many in the magazine (all 8)? Not enough lube on the gun?
A pat on the back of the slide solves the problem, and it usually happens when I release the slide by pulling on the back of it rather than releasing the slide release with the trigger finger. So there. Easy fault fix. And use more lube.
Never happens with my Glocks!
ReplyDeleteMy XD and Sig's are fine. Are you trying to say the slide does not fully close and you have to pat it closed?
ReplyDeleteWe should try those mags in my 1911 to see if it's the mags or your gun.
ReplyDeleteslide does not fully close, it is hung up trying to cram that bullet into the chamber. like it's rear end is hung on getting under the extractor or the feed ramp is jamming it to the roof of the chamber at a cocky angle. And I have done nothing to alter this area of the gun apart from cleaning it with a tooth brush.
ReplyDeleteIt's happened like 4 times. Always with the 8 round mag and its strong spring, and always when I haven't put any lube on the slide. Usually with one of the first to feed, I beleive, and probably with just the Remington ammo, not the Magtech or very few Winchesters. FMJs, all.
Examine the innermost edge of the feed ramp, where it joins the chamber proper. It it looks or feels like it has a sharp edge, consider polishing it with 400 wet-or-dry paper wrapped around a pencil. Just enough to break and polish the edge. Also examine the corresponding area on the underside of the barrel hood. Some guns (and mags)pop the round up at the back and this can be seen by a crescent mark on the brass, and the occasional jam with the round up in the back. Feeding the first round probably saps most of the energy in the recoil spring and there's not enough left to complete locking up if there's a little extra friction.
ReplyDeleteI recently bought a Kimber SIS and I have been having the same issues. I sent it back to Kimber, they "reamed and polished" the chamber and changed the extractor out. It worked much better since then, but I still get the same jam about once every 100 rounds (instead of once every 20 rounds like before).
ReplyDeleteI am using the Wilson ETM mags myself and would LOVE to find out exactly what the problem is.
