Hi all,
I'm new to 1911's and this forum. I've had my RIA 1911 for about 3 months now and have only put about 100 rounds through it (pandemic ammo prices). During that first range session, I had 2-3 rounds jump in front of the extractor, preventing RTB. I've also been doing a LOT of dry fire practice with A-Zoom snap caps. I've had this problem happen randomly here and there when practicing (maybe 5-6 times in about 300-400 cycles), so it's not exactly an "every-other-round" issue. However, its enough of a problem to cause concern for me. I've had this issue occur with the factory magazine as well as with several new Wilson Combat 47D magazines, so I don't think it's magazine related. I know that 1911's have a break-in period, but I'm wondering if this is normal or if it might be improper extractor tension or something else abnormal.

Thanks!

Given that you've tried Wilson mags which I'm not a fan of personally but I was going to suggest the mag or the mag spring more specifically...an inertia feed where the mag looses the round on (rear) recoil before being stripped from the magazine as the slide RTB.

I thought it was 'Last Round Jump' too, but he says it does it without firing. Apparently the round is jumping out of the mag when he retracts the slide, so it is out of the process and will just stop the gun. Definitely magazine-related if this is what's happening. Oiling a magazine that's a little 'iffy' could cause it but it sure sounds to me like the round is turning nose up as the slide moves back over the base, and normal mag spring action completes throwing it out of the mag, or it turns straight up, still caught by the base, and the returning slide just pushes it out of the mag that way - either way its a stoppage. Might have to experiment with one mag that does it a lot by pinching the feed lips a little to see if it can be corrected.
With Snap-Caps or dummy rounds, watch as you retract the slide on a full magazine to see if this happens.

Any 1911 may need a touch of fine tuning. If I get one that requires absolutely nothing, great. I pretty much have my head wrapped around the fact that I am in for an hour or so of adjustment with a new purchase. Sometimes more. I am not in the “fire 1000 rounds before you call us” camp. It usually doesn’t take much. I find joy in the problem solving. Regardless of price point of the gun. I have not found pouring 1000 rounds through a gun to “break it in” to be efficient.

I also find perverse joy at the range with the crowd that claims 1911 are not reliable and therefore a Glock (fill in the blank...) is more reliable. Or that the RIA (fill in the blank...) is not reliable. 1911’s can be as reliable as about anything. And about as trouble free. And then buzz through 300 rounds without a bobble. On every range trip.

Steve’s sticky on extractor fitting is excellent. My guess is that a few extractor tweaks and you are done.

This happens when a round leaves the mag by inertia and comes out unescorted by the breech face. Clean and dry your mags, no oil.

Thank you all for the replies. I'll definitely be looking into extractor tuning. I also heard about inertia feeding, but I have had this issue happen when loading a new magazine with the slide already locked back. When I insert the magazine and send the slide home, it fails to RTB with the rim of the snap cap in front of the extractor. I spent about an hour last night trying to induce the malfunction with several magazines, but it ran fine. It seems extremely random. I may also give RIA a call and see what they say, I heard they have pretty good customer service.

...and this can happen by the stripper rail bumping the round and it flying out, before sliding up the breech face. One point to also consider is that the extractor is tuned so as to be able jump the rim. I tune mine so if a round is in the chamber the extractor will jump the rim with the slide released from a half way point.

Ball ammo? SWC? Hollowpoints? The type of ammo is the starting point. How about a photo or two of a feeding round?

According to your description, the rounds jump in front of the extractor. If that is true, the feeding round has been released by the magazine too early relative to the position of the slide. Guess what the Wilson 47D is designed to do...release SWC rounds early so they have a chance of bouncing around and eventually feeding. 47D's work differently in each 1911, primarily because the gun was not designed for SWC magazines. Your factory mag may also be a SWC - photo please.


I know that 1911's have a break-in period
No, this idea about gun break-in is a myth originated by irresponsible writers in the gun mags and customers who are willing to accept poor workmanship as the norm. Sure after a few thousand rounds your trigger pull might be marginally smoother. But the gun should be 100% as new.

Fooling with the extractor might change things a little, but that is not your basic malfunction. Barrel setback, feedramp depth and angle, VIS dimensions - many times the manufacturer never checks them out.

Adjusted extractor, polished feed ramp. You do not want to hear this from factory service. Finally, the 1911 and the magazine that is designed for it (which you probably do not have) work as a unit. The pistol was designed to load and fire under ugly circumstances, including rain, mud and oil. Ever hear of a 1911 pistol that got a guy killed because the magazine had some dirt or oil on it? Give me a break!

Please follow up on this problem and let us know what happens.

Okay, you are giving us conflicting stories on what's happening. So now its happening on the first round in the mag? In that case it is obvious that your extractor needs tuning. Take the slide off the frame and take a complete round and manually slide it up the breech face so it gets under the extractor claw, then let it hang. Is it held tightly to the breech face? Does it fall out? Does it hang at about 10-15 degrees?

If the round was ever under the extractor, it would not be able to get in front.

I figure the extractor doesn't have adequate clearance for every round to be caught, or is deformed in some way that makes it seem like that. Doesn't hurt to get a few metrics on what's actually happening.

Thank you for the reply. Just to clarify, when dry firing with snap caps, I have had this happen on the first round. When live firing, this happened mid way through the magazine (3rd or 4th) round. Sorry for the confusion.
