Feeding and Ejecting Issues. Tisas 1911 Duty

This post is lengthy but I’m trying to provide as much info as possible!

I recently purchased a Tisas 1911 Duty 45acp and put roughly 800-900 rounds through it and starting to see 2 problems: Feeding issues and the ejection of the shell.

I do a field strip cleaning after every range visit

1. FEEDING ISSUES - first day I bought the gun I put about 200 rounds down range. Right around the last mag, the bullet got stuck while entering the chamber. It was the last round of the mag. I figured the gun was still in the break in phase, so I wasn’t really concerned. I was using Magtech 45acp 230fr FMJ ammo (all they had at the range)

Next visit, same thing happened but worse. I picked up a box of Blazer 45acp 230gr FMJ and the gun did not like this ammo at all. It was like every other mag the gun would jam like I mentioned above. I bought another box of Magtech ammo and the gun worked fine until the last mag, were the gun jammed on the last round.

The next couple of range visits, I shot only Magtech ammo and each visit the gun jammed on the last round of the last mag! (Each visit was about 150-200 rounds). I was getting pissed because I was damn near over 500 rounds in and it’s still giving me trouble.

I bought 2 Wilson Combat mags thinking the stock mags were the issue. On my next visit to range, I decided to switch up the ammo and bought 100 rounds of Remington 45acp 230gr FMJ. The gun worked flawlessly! No jams! I ran out of ammo and bought a box of Winchester 45acp 230gr. On the first round of the first mag (Winchester ammo) the gun jammed. I was able to finish the box of ammo with no issues.

After the new mags and different ammo the gun was working fine! Until the second problem occurred; the ejection of the shell (FYI the feeding issue is not resolved.. keep reading)

2. EJECTION OF THE SHELL - lately, the trajectory of the shell has changed. No longer goes off to the side. Instead, it’s coming back at my face. But only when im near the last couple of mags. No jams though..

Yesterday I was at the range and the gun was working awesome! I thought my nightmare was over.. about 50 rounds in one of the shells came back and cracked me on the forehead and then jams while chambering the very next round! I literally packed up my gear and walked out. lol

IN ALL - I’m about 800-900 rounds in, changed the mags and ammo. Still having feeding issues. I’ve noticed that problems only occur when I’m getting near the end of shooting. I go to range with a clean gun and then after a few hundreds it gets dirty and gives me trouble

Maintenance

• Field strip cleaning after every range visit.
• I use Ballistol for cleaning and lubricant

New Mags
- Wilson Combat

Ammo brands used (all 230gr FMJ)

• Magtech
• Blazer
• Winchester
• Remington (no issues)

The ejection of the shell is going the wrong direction.. I did a detailed strip to try and figure out what the hell is going on and I found some pretty interesting things.

Ived attached photos of the ejector and tried my best to get a clear shot of what I believe to be a damaged ejector?

I don’t have a photo of the extractor but it was the dirtiest part of the gun. I mean it was caked with black gunk

WHAT I NEED HELP WITH -
1. How do I fix the feeding issue (don’t say buy a better gun..)
2. Is the ejector damaged?
3. Is the dirty extractor getting stuck and preventing the next round to come in? (Idk I’m just asking)
4. What ammo do you use for target shooting?
5. ANYONE WITH THIS GUN HAVING THESE ISSUES!? lol

I hope someones feedback can help me! Thank you!

I like to "get an extra round in" as well - but I just insert a loaded mag, cycle one into the chamber. Then I put the safety on, drop the mag, and load one more round into it before putting it back into the gun and into the holster for carry.

This is what we call a clue. Remove the extractor from the slide. Clean out the tunnel it goes into. Lots of solvent, soaking, and scrubbing with a .22 bore brush. Keep cleaning it until it's as clean as a whistle. A gunked up extractor tunnel can cause failures-to-feed since the extractor cannot easily flex outboard because of the built up gunk on the outboard side.

Feeding issues can be the result of more than one thing so there is no quick fix. All you can do is try one thing to see if that fixes it. If it doesn't, you try another thing and so on until it's fixed.

A simple diagnostic is the first thing you can do to try to isolate the problem. It's called the plunk test and should be run with each brand of ammo you have.

1. Remove the barrel
2. Hold the barrel muzzle down, chamber up
3. Drop a round into the barrel. You should hear a distinctive sound when the brass case mouth hits the steel chamber ledge
4. While pushing the chambered round forward hard, rotate it. It should easily rotate as the brass case mouth slides around the steel chamber ledge. If it doesn't rotate easily, send the pistol back to the manufacturer and have them finish ream the chamber.

It doesn't appear to be damaged. The slide may not be coming all the way to the rear due to really weak ammo or too heavy of a recoil spring. A 5" .45 1911 should run perfectly with a 14lb or 16lb recoil spring. If your pistol has a heavier recoil spring, I suggest replacing it with a conventional Wolff spring either 14 or 16lbs.

I use 200gr HG68 reloads and I run a 14lb recoil spring in 5" 1911s.
