Colt 1911 Constant FTF

[Wolfgang7]

Hi all. I recently replaced my slide lock on my Colt MKIV Series 80 Combat Elite. Had it out at the range for the first time after replacing and had constant Failure to feed. Multiple times it was like when it cycled it just jammed the next round into the feed ramp. A few mags cycled no issues. Slide lock seems to lock back on an empty mag and drop the slide on a full one. But more mags than not it would FTF many times. Tap Rack sometimes solved the issue other times took some convincing to get the mag out and get it going again. Could this somehow be related to the new slide lock? Or maybe sheer coincidence? I maybe got through 60 rounds and eventually stopped shooting it as it clearly seemed suspect and was a constant issue. Never had this issue before at all! Any input greatly appreciated! Thanks in advance!

And to be clear this is when firing the pistol, instead of chambering the next round it FTF's

You changed a part and now the thing doesn't work and your question is, "could the problem be that part?"

Put the old part back in and you will have answered your own question.

Wonder of the new catch is pushing up the follower, causing it to nose dive the round.

Or change the geometric of the follower.

There is simply too much power in the 45. I have been told this many times!

Make sure the slide stop is not binding in the link and that the barrel travels fully around the slide stop. A weak recoil spring or damaged/misfit extractor can cause issues.

Yes excellent idea! I didn’t have the old one at the range with me, but will definitely take next time. Thanks

Hmm I’ll take a look. It definitely seems like the round is “nose diving” as you put it

So took a closer look. Looks like the next round being pushed up by the mag is catching the inside of the slide lock and being angled down then when the side cycles it’s just driving it into the feed ramp. I cycled some dummy rounds by hand and happens almost every time. The first round chambers only if I load the mag with slide locked back , which makes sense cause the slide lock is out of the way. Any round after that gets caught and driven into the ramp by the slide. Think this means the new slide lock is slightly out of spec or possible other issues? Any input is greatly appreciated !!

1911 parts are not ‘drop in’ parts. No two parts will function in a pistol factory fresh. Almost all of the replacement parts I’ve installed on my 1911 have required some type of ‘adjustment’ when installed to allow my pistol to function properly.

Barrel bushings are always slightly oversized so you have to fit them. Slide stops as well. Check pin diameters as well as the follower plate protrusion to ensure the fitment to your barrel link and magazine choice is accurate.

We won’t even start on grip safeties or thumb safeties. There are jigs for that.

Enjoy your pistol, but understand that it’s not a Glock. It takes thought and care to keep it running right.

Sounds like the sort of thing that can be adjusted in 2 minutes, with a fine file.

Here is one of mine. The mag is not fully seated, instead it's sitting a bit low so you can see how much clearance a RN bullet design has going past the slide stop.

Thanks for this !
