Hello everyone

I want to start doing my own work on my own gun. . .

New to this area I have a problem with my new Citadel 1911, now I dont need to here things like “yes, the problem in that it is a Citadel” I need to fix what I have. My new Citadel 1911 jams all the time, does not seem to matter what kind of ammo I put through it, it jams, now, I have already taken it to the gunsmith because all you had to do was pull the slide and it would fire, with that fixed, now, the bullets jam, the tip of the bullet jams right on the feed ramp, what I need to know from all of you is, can I grind down the leading edge of the feed ramp and widen out the area the bullet rides through without causing and problems ? I will make sure to polish it after Im done. Is this a bad idea ? Please let me know.

I wouldn't start "grinding" on the feed ramp. First thing- does this happen with standard 230 grain full metal jacket (ball) ammo? Have you tried it with other than the stock magazine that came with it? Do you know anybody who has a 45 that functions reliably and that you can borrow a well functioning magazine from? Have you thourghly cleaned and lubed it? If you've tried all of the above with no luck, call the manufacturer/importer and send it back. I'm sure if you start "grinding on it,it will void your warranty.

Is the rim of the case contacting the extractor when it rams the round into the feedramp?

The very LAST thing to do is grind on your pistols feed ramps.

Send it back to the factory.

Sounds like you're headed in the direction to only make things worse.

Most 1911 malfunctions are caused by ammo, magazines, poor extractor tension.
Rarely, if ever, are they caused by a feed ramp problem.

If the tension on the extractor is to tight it can cause this also. Check that first. Improperly tensioned extractors send a lot of 1911 owners on long expensive wasted quests.

Get Vol 1& 2 of Kuhnhausen's 1911 shop manual if you plan on any 1911 work.

GOOD GRIEF! $198? That is freakin insane. You can buy both volumes direct from the publisher for a fraction of that.

Monumentally bad idea as a DIY project.

Check the slide stop lug to make sure the bullets aren't catching it as they come up out of the magazine. Take the slide off for this inspection.

If you see brass rubs on the slide stop lug, a few careful strokes with a file will usually provide enough clearance. It's important to leave enough material that the lug will engage the follower.

You're not alone... I picked up A Citadel this afternoon, my first 1911, and ran into the same issue. I'm using Winchester 230gr personal protection and 200gr+P Gold Dot JHPs in both Act-Mags that came with the pistol. I think it is a mag issue with mine. As soon as the slide makes contact with the edge of the rim the bullet goes down and into the feed ramp. The extractor does not make contact with the rim. The mags are difficult to unload by hand, they tip nose down with any forward pressure and it feels like there is a snag point when unloading a mag by hand.

This is probably caused by the ammo not laying correctly in the mag. The top bullet in the mag does not lay flat against the round beneath it, instead it is held in place by some half assed spring tension not strong enough to hold the bullet nose up. See picture:



I'm new to 1911s, but that gap/lack of spring support looks to be the possible cause of my problems. Someone let me know if this is a normal condition for a single stack mag, I have never owned anything other than double stack mags, and my double stack mags do not do this. This is just my best guess.

my only suggestion is to try a better quality mag and polish not grind the feed ramp.

Picked up a CMC and a Wilson 47D. The CMC feeds the Winchester PP JHPs but balks on the Gold Dots. The Wilson fed both loads without problems. All of my mags fed FMJ without any issues.

Kuhnhausen suggests your problem is the result of the magazine releasing the bullet too late. So, slightly widening the lips of the mag to allow bullet to rise sooner is his suggestion. If you start getting stove pipe feeds, you know you've opened the lips too much. Somewhere in the middle, there, is nirvana.

A polished ramp is always a good thing. Grinding on a ramp usually not a good thing.
