1911 won't feed HP

New or used? (the firearm, not the ammo)

Start easy, troubleshoot by trying different: magazine, ammo, and recoil spring if its used (one at a time of course). Ended up being the recoil spring for me on a supposedly "lightly" used 1911.

I've outlined a few common problems along with the steps that need to be taken to identify exactly what's causing the malfunction. Too many inexperienced guys have attacked the barrel throat with a file or a Dremel, when the trouble was the extractor. By the time they realized their mistake, a barrel was ruined. The bottom line is that it's 10% knowing where to look and 90% common sense and patience.

Some feeding issues with short HP's and target wadcutters are remedied by tuning the magazine lips. The short nose requires an earlier release from the magazine as the slide is closing.

Where do the rounds hang up?

STI is a high end gun and it might like specific ammo, so it might be the reloading territory.

As an example, my fully custom hand built SVI will not always feed reliably off the shelf target fodder. The recipe I have from the manufacturer is for OAL of 1.200, not the 1.135 which is the SAAMI specification. Such long rounds won't even chamber in standard .40 guns.

I’d start with the rounds themselves. The rounds could have come from the factory in working conditions, but thru handling set back could have occurred. The primers could also be not flush. If you set the bullets on a table standing up, do they wobble?

If you have a reloading buddy, use their case gauge to check the ammo.

All my self defense rounds are first checked before they’re even loaded. In my opinion, every self defense round should be checked before being loaded.

I've had two different 1911s that didn't like any of the Hornady Critical D or Custom ammo. Everything else would feed fine. The explanation I got was the Hornady stuff is manufactured on the large end of acceptable standards. When you combine that with a tight fitting chamber it causes problems. I never got the calipers out to verify if that is true or not.

Try doing a plunk test to see how the Hornady stuff fits. On both of my guns they would hang up.

If nothing else works, I'd consider sending the gun to a gunsmith.

1. Buy Wilson Combat ETM Mag
2. Try the Hornady again
3. If it won't feed Hornady, try Federal HST 230 Gr

If it won't fee HST's call STI and see what they suggest.

Great article. I have a 1911 that feeds ranger all day long but not hydra shok

So I shoot ranger T series.

Are they oem mags? Could be a high end gun with cheap mags.

any issues with JHP without a flex or plastic tip?
