M&P Compact 22 Failure To Extract

[BillG174]

I bought a new M&P Compact 22 in December of 2015 and it currently has 3700 rounds through the barrel.

It has a tendency to experience failure to extract. I have used Federal, Remington Golden Bullet and am now using Blazer 22LR ammo. The gun has failure to eject issues with each of these ammo's.

Two days ago I cleaned and lubed the gun according to S&W's user manual then I went to the range with the Blazer ammo. The gun shot fine but then had several repeated failure to eject. The fired cartridge remained in the barrel. I disassembled the slide so I could get to the chamber better. The fired cartridge was "stuck" very tightly in the chamber. I had the range RSO use a large pocket knife to hook the rim of the cartridge with the pocket knife blade. We were finally able to remove the cartridge. It's pretty frustrating when it happens repeatedly.

The cartridge appears to be very tight in the chamber and I am wondering how the extractor can get in and under the cartridge rim to grab ahold of it to extract the round.

Does anyone have this issue and does anyone have suggestions on why this is happening and how to fix it?

Thanks! Bill

Could be as simple as getting the chamber COMPLETELY CLEAN.
Oil or grease left in the chamber can bake on.

By chamber do you mean the rear end the barrel by the feed ramp where the round feeds into or the entire length of the barrel?

Yes, you need to scrub it clean with a bronze bore brush & a solvent such as Hoppe's #9. Another thing, make sure the bolt face is cleaned of any carbon deposits. The bolt face is the part of the slide that contacts the rear of the cartridge, where the firing pin comes out to make contact with the shell. Make sure all traces of carbon are gone. You may have to use a small pick or similar tool to scrap the carbon out of tight areas

I'm seeing some confusion between fail to extract (remove the casing from the chamber) and fail to eject (pop the casing out the port after extracting it).

Two different issues.

Fail to extract -
**** under the extractor - clean with the slide muzzle end down so junk does not run into the firing pin channel. Go at it with a nylon brush. And, be sure the extractor cut in the chamber is spotless. Be sure the extractor moves as expected and is not chipped or broken. If so, CS will arrange fixing that.

Fail to eject -
Be sure the ejector arm is clean and straight. I discovered (the hard way) that this is easily bent if you fail perfection while cleaning the barrel with a rod from the breech. I whacked mine out of alignment. S&W CS fixed it for me.

This (these) issues are not that unusual with .22cal. Hoc9sw is likely correct: Cleanliness with an often used .22 is crucial. It's amazing how fast residue can build up behind the extractor claw and pivot area, reducing its movement and thus it's ability to grab the rim, which is minimal in the first place.

The same applies to the breech/chamber area. Thorough cleaning goes with frequent use. I have had a S&W model 17 since new in 1983. It is one of the finest .22 revolvers in the world. No sane person would disagree with that, but, it had a problem with sticking brass after a couple hundred rounds at the range for many years. I ignored it because I was aware of why it was happening and simply did a quick wipe after every box of 100 round. The cylinders needed to be honed. This was done last year and there has never been a problem since.

I'm not saying your gun needs that kind of attention, but it does need to be cleaned more thoroughly than a larger cartridge weapon. In my experience, .22's are dirtier than other cartridges. They are produced in greater numbers and fired in greater numbers than almost any other round, and are cheap. People tend to go through many more rounds during shooting sessions because of that fact. The guns get dirtier and need more attention in all those tiny nooks and crannies.

Do that and I think your problem will become far more rare.

I polished my feed ramp and chamber with my Dremel, no problems!

I make them look like chrome, they are quite rough from the factory!
