I'm having issue with a combat commander that occasionally fails to return to battery. By occasionally, I mean between one to three percent of the time.
I made it to the range today and brought relatively new magazines with me. Fortunately, I only had one jam out of one hundred. Unfortunately, it was the same jam that has plagued this gun since the new barrel was installed.
The magazine was an 8-round WC ETM and happened on the sixth round. Same jam as before, under the extractor hook and kinda sorta wedged up into the chamber. I've experienced the same issue with the factory colt 7-round magazines and factory Springfield 7-rounders.
In the past, the jam has happened when chambering the first round from slide lock. This is the only time that it has shown some kind of pattern, as it usually happens with JHP ammo. However, the brand doesn’t seem to make a difference and it has happened with FMJ as well. Ninety-percent of the time, I can push the slide into battery with a light tap. If not, the round can be extracted by racking the slide.
As I mentioned before, the issue is seemingly random. So far, I’ve experienced it with 230 grain Winchester Ranger JHP, 185 Federal JHP, 230 Federal FMJ, 230 Freedom FMJ, some other random stuff. All factory new. Today I shot through a 100-round box of 230 grain Federal JHP.
Most frustrating, is that I’ve never been able to intentionally recreate the issue. It is always the first round, from slide lock, or in the middle, but never the last round. It isn’t as if the gun is excessively tight by any means. In fact, I think it is rather loose. I don’t slam in the magazines on an open slide and do my best to make sure the rounds are seated properly in the magazine.
Photo shows the same failure and the round that it failed on. Nothing special from what I can tell. I reloaded the same round into the same magazine and fired all three shots without issue.
Things I do know. It has never happened on the last round. The round is always under the extractor and can be ejected by racking the slide. It doesn’t seem to matter the make of magazine or type of ammo. It is the only type of jam I’ve ever had with the gun. No FTE, no failure to pickup a round or inertia feed. I recently put a wolf 20-pound spring in it and you can ride the slide forward to the last breath without being able to recreate the issue. I've put around 600 rounds through the barrel. It ran like a champ before the upgrades, but shot a pattern at 25-yards. It is now the most accurate pistol I own.:rock:
I've shot 1911s pretty much exclusively for the last few years and never had an issue. The gun has been cleaned after each session and lubricated with Slip2000 EWL or slide glide. The lube didn't seem to make a difference.
I've sent the gun back to the custom shop that did the work once already, but they were unable to recreate the issue during their 50-round test, which isn't surprising. It is hard to fix something you can't see. Customer service has been excellent.
What can it be?
