 9mm 1911 Feeding Problem

Hey all,

I've been working on this problem for a few weeks now and it's to the point where I'm frustrated.

I have a Fusion 1911 in 9mm. I've got some nine-round mags as well as some Metalform 10-round mags.

I can load the mags anywhere from one round to full and it runs fine with one exception:

The second to last round often hangs on the edge of the barrel, failing to feed.

I loaded up a bunch of rounds without powder and primers and have been hand cycling it and that's about the only place it ever has a problem. I can load three rounds, chamber one, cycle it and it hangs. Or I can load 10 rounds, cycle it until I get to that second to last round and there it hangs. The last round feeds fine once I either get the previous cleared or chambered.

This also happens from slide lock. I can load a mag with three rounds, chamber a round. Cycle the slide and lock it back, then drop the slide and it will often fail to feed. Any other point in the mag works fine.

I've tried adjusting mags, trying all the mags, etc. but it seems to happen in ALL the mags. It doesn't happen every time, but most of the time.

It seems like that second to the last round just is not coming up far enough and I don't know how to correct that.

Was hoping someone could provide some suggestions on how to proceed. The gun has about 570 rounds through it so far and the mags are pretty new. Other than that one problem, it runs and shoots great.

Thanks for any help.

I'd say it doesn't like your mags. Most likely the follower design. Try a Tripp Research 9mm Cobra Mag

Had a feeling that would be the suggestion.

Any idea why all the other rounds would feed but just the one wouldn't? That's what really confuses me.

I'd considered trying different mags, but didn't want to buy a bunch new if that wouldn't be the fix.

As for the Tripps, are those better than the new Wilson mags out? Also, I see that the followers are available from Tripp. Would that be an alternative is to just order new followers for what I've got, or would I be better off ordering all new mags?

Thanks for the help.

I think the Tripp cobra mags are the best thing going, just my personal opinion. Were I you I'd order just one mag and see if it eliminates the problem.

Thanks, as always, for your help.

I'll place an order and try out the Cobra Mags.

I assume from your description of the FTF you are not using a ramped barrel? what type of bullet are you using? Hollowpoint, ball, etc? What pound recoil spring are you using? Try using a standard 9 round magazine, with a Wolf extra power magazine spring.

Also, I had put together a couple of 9mm 1911's using Caspian Frames and converted a Springer GI model in 45 acp to 9mm. I eventually got them all running with out ramped barrels but only using ball ammo. I did have to tweak the barrels and throat them out a little. I used sanding drum with a dremel.

I was using a couple of Fusion non ramped barrels. The Commander barrel worked fine, but I sanded the government barrel to get it to feed reliably.

They all sport ramped barrels now. the springer is using a ramped Fusion barrel. I think the only way to go 9mm is with a ramped barrel All the expensive pistols use ramped barrels. They will gobble up hollow points without a hiccup.

Questions:

1. Ramped or non-ramped barrel?

2. If non-ramped, is the frame ramp angle correct for 9mm? I'm guessing that this is the Fusion kit you mentioned you were having a problem with last month. Could it be .45 ramp angle?

3. Has the barrel been properly throated?

4. What bullet profile & OAL? Have you experimented with different OAL's?

5. What kind of load are you shooting? How far does the ejected cases fall from the gun?

6. Can you post a photo of the FTF?

On seeing the thread title, I was also originally inclined to the ramped vs. non-ramped question.

But seeing that it always hangs up on a specific round - and only that specific round - from the mag, this really sounds like a wholly mag-related issue.

That's what my thought was.

Ran up to the range tonight and had the 10-round mags functioning pretty well. I bent the follower up just a little bit and they weren't hanging. I couldn't get the nine-round mags to work.

The nine-rounders may be a lost cause as they have the welded base plates.

As for the questions on the barrel, it is non-ramped barrel. I think the frame is fine as I got it as a 9mm frame and it does seem to run fine the rest of the time.

Only bullets I've tried are RN profile. I've ran some WWB and reloads. Haven't experimented too much with different OALs, but have considered trying that as well.

Looks like I've got a good list of things to trouble-shoot and try should I continue having the problem, and I appreciate all the help.

Here's a pic of what it looks like when it won't feed.

Round just goes straight forward, not up at all, and hits the edge of the barrel.

From the looks of the picture its a lo hit on the chamber mouth of the barrel. I saw a ton of those when I was working on my nines. I took a Dremel with a sanding drum and only where the round was hitting the barrel, I put more angle leading in to the chamber. You don't want to much because the case is not fully supported in this area.

There are safety concerns.................upgrade standard metalform and or Mecgar mags with wolf extra power springs.......Thats all I run in my guns. I can't see 30 bucks and up for a single stack mag. If commander use a 16 pound spring, In my two Gov'ts I'm using 15 pound springs.(RECOIL SPRINGS)

Then ask yoursef...........do I love this gun and wan't to keep it awhile...........If the answer is yes, get the frame cut for a ramped barrel and be done. The 1911 in 9mm is a lot of fun, low cost to shoot and is a lot easier to control under fire.

I can't tell from the photo what the ramp and barrel surfaces look like.

Is the the bullet nose catching on the bottom edge of the barrel?

If so, does the bottom of the barrel have a sharp edge?

Does the bottom edge of the barrel set proud of the frame ramp when the barrel is all the way down and back?

Why don't you bring to the match next weekend and let me take a look at it.

That's what I'm thinking.

The very front of the nose of the bullet is going straight into the bottom edge of the barrel.

Thanks for the info you've been providing as well. Do I love it? When it runs.

I definitely plan on keeping it, just a matter of getting it all figured out. And yes, I am thinking I should have gone with a ramped barrel in the first place.

I'm definitely going to look into all the various magazines/options/upgrades there.

Thanks again.
