My MkIII 22/45 Lite is FTE-ing

Hey guys. I love my 22/45 but sometimes it doesn't act the way I want. I shoot Win 333's and Federal 525 ammo. The Federal is better than the Win in my opinion. But they both sometimes fail to eject. I will shoot and then when I go to shoot again I just hear a click. The fired shell is still in the chamber! Didn't even eject.

It also FTF's sometimes too.

It does it dirty and clean... AND I have a VQ firing pin and extractor, which is supposed to fix all problems. I have read the magazines can cause problems? I have one magazine that has the lips ground down and I think on occasion it has happened with that one as well. Any ideas?

I am pretty sure I am not limp wristing it
 
Other than making sure it's clean I can't help you right now. I have a mkiii competition slab side. It works flawlessly. I have put about 9000 rounds through it with only about 10 miss fires.
 
I had the same problem with a new MK III and like you I changed the extractor. The difference is mine was fixed and yours is not. I wonder if there is a very small bure in your chamber?

Use yellow jackets. Mine never has issues with the high / hyper velocity. It like the extra charge. Because of the low charge, most .22 auto loaders will have FTf or still be pipes periodically.
 
First off stop and realize that with a direct blowback design like this the extractor is simply along for the ride. It does not actually pull the empty casing out at all. The pressure of the firing makes blows the empty back and the empty actually pushes the bolt back. The extractor hook does nothing until the edge of the casing hits the ejector. At that time the extractor hook acts like a pivot point for the casing which is pushed and spun off to the right by the ejector.

So if you're finding that you still have an empty in the chamber but it is re-setting the hammer it would seem that the bolt is not going back far enough. If it doesn't go back far enough two things fail to occur. First is that the empty does not reach the ejector so it never gets knocked out of the bolt face where it's held in place by the extractor. Second is that it does not go back far enough for the lower lip on the riding edge to let a new round snap up in front of it. If it were going back far enough to pick up the new round but not far enough to eject the empty then you'd be seeing a different sort of jam.

So the issue would seem to me to be a case of the bolt not going back far enough. What are you using to lube the bolt and how much of it are you using? You want the bolt to be LIGHTLY oiled with a typical gun oil. If you soak it with too much oil it'll be like trying to wave your hand underwater vs waving it around in the air. And it requires VERY LITTLE oil to do the job in any case. If you're using something thick and greasy then it might again be slowing the bolt down due to the viscosity of the lubricant. Maybe play around with some different oils to find one which makes the bolt move more slickly. Also there is one place where I find grease works well. It's on the heel of the bolt where the hammer rubs and along the spine under the bolt again where the hammer rubs. A light smear of grease on this fairly high pressure contact point can really smoothen and slick the bolt operation up nicely.
 
My MKII did the same thing.

I thought I had cleaned everything properly, but after a couple of cleaning cycles and range visits with disappointing results, I discovered that I hadn't taken it down far enough. I had scrupulously cleaned everything on the top end, but I hadn't taken down the main spring and the bits associated with it in the handle. It turns out the extra drag was causing a short stroke that resulted in a FTE or a stove pipe. Once I took it completely down and cleaned all the bits inside the handle properly, it behaved as expected with just about anything I ran through it.

The Rugers are a bit of a pain to strip compared to other pistols, but after watching a few YouTube videos of how to completely strip them, it wasn't too bad a job.

Good luck -- they're a great, fun little gun most (almost all) of the time.
 
I've tore it down completely and cleaned it. But I guess I will try some different lubes. Maybe some grease...maybe polish the hammer face?

Is there lighter strength springs I can put in?
 
If you can find some Blazer 22LR it is somewhat hotter than standard velocity ammo (1200 FPS) if I remember correctly, it's been awhile since I have seen any.
The added recoil might be enough to run your gun reliably but won't pound it like high velocity ammo will.
