Combat Commander Jamming

My Combat Commander is jamming. It doesn’t do it every time but usually 1 to 2 times per mag, sometimes more. Every once in a while a mag will run without issue. The jams happen in all positions of the mag, not just the first or last rounds.

It doesn’t seem to matter which mag I use. I used the following:

- Colt 7 round
- Wilson Combat 47D 8 round
- CMC Classic 7 round

I have my own ideas as to the cause, however, I know there are many people here who know a lot more than myself. I don’t want to sway the conversation with my own ideas.

Hard to evaluate based solely on pictures but they would indicate an extractor issue.

I should note that ejection is erratic as well.

It seems that the extractor is losing its grip on the case. Check the extractor tension and adjust if needed.

I just ordered a WC BulletProof Stainless Extractor. The one currently in the gun is blued so I know it isn’t original. Instead of messing with that one I’m just going to properly replace it.

Try this - remove the extractor and see if rounds feed reliably without it. If they do you've found your problem. The photos look like an inertia feed problem (which is usually weak magazine springs) but we really need to examine the gun itself. A new extractor likely will not drop in and run without some tuning like setting the correct mount of tension and breaking the corners of the hook slightly. Are the rounds in the photo unfired rounds or rounds that fed and fired and then failed to extract?

As one would normally expect, the gun feeds rounds flawlessly if there is nothing in the chamber. I don't need to remove the extractor to confirm this, the first round of a new magazine has never hung up.

I mentioned earlier that I had my own ideas as to the cause and I'll lay it out here:

1.) The gun is in battery and a round is fired.
2.) As the slide retracts the extractor comes off the case head. Whether it is due to being under-tensioned or worn I can't be sure.
3.) The slide begins it's forward motion to return to battery, as it strips a round from the magazine the round is stopped by the underside of the partially extracted case that is still in the chamber causing the gun to jam up.

Another symptom that occurs is the cases that are successfully extracted are ejected in an erratic manner. Some straight up, some to the right, some to the forehead, etc. This seems to me to go along with a worn or under-tensioned extractor as the case is not held firmly enough and is not always in the same position when it hits the ejector.

You can confirm this by simply taking the barrel out and slide a round under the extractor, also check the condition of the hook and make sure it is not more than 90*.

I'll check when I get home just to satisfy my curiosity. However, since the extractor is blued and the gun is stainless I'm going to replace it anyway with the Wilson Combat Bullet Proof Extractor that I ordered last night which will be here tomorrow along with a whole heap of other parts.

The new extractor will prolly need to be fitted/adjusted. I've seen several guns that needed adjustment when brand new.

Since you are going to have to tune the new extractor, why not tune the one in the gun now, get some practice. You might find out the old one is ok.

I'll tune it but it's getting swapped out regardless due to the color.

LOL!
We have our very own 'Uncle Nick' giving advice here.

h4,
There is a great sticky by Steve from Allentown on tuning extractors at the top of this page.

Here’s a couple pictures of the extractor that is in it. It looks like it is clocking along with having way too much radius on the claw.

To me, the extractor looks too worked-over to salvage and the firing pin stop is not helping hold the extractor effectively. I would get new parts for both. The Sticky from Steve in Allentown is the best method of fitting the extractor, ever. It just works. IT discusses shape, tension, and displacement. It does not require special tools. Just a little patience.

Shape the extractor per the instructions, including the fit between the front of the hook and the tapered part of the case. Get the tension right and the displacement correct as he advises. You will love the results and the Commander will run like an appliance.

I had a Springfield that was very touchy WRT the extractor and was giving me intermittent fits. After following the instructions, it is so boring to shoot! It just runs and runs now

A new Wilson BP extractor showed up in the mail today and the Wilson FPS will be here tomorrow.

I read through that sticky earlier today, it is extremely informative.

Those problems with the extractor explain my issues though.

I was looking at a stainless combat commander at the gun store on Friday.
You could actually clock the extractor by hand, it was that badly fitted.
It would rotate a couple of degrees anti clockwise, and then you could push it back with thumb pressure.
