Double Feed/Failure to Extract With Low Round Count Shield 9

Last week I had a nasty jam with my pistol. I drew, fired two rounds, and upon transitioning to the next target found that the slide was not in battery. While locking the slide to the rear I noticed a casing halfway out of the chamber, similar to the attached picture. Video of the stage showed no ejecting brass. The brass fell free when I stripped the mag and was not recovered.

The pistol was purchased new in December, is still stock internally, and has about 500 rounds through it, approximately 100 rounds Remington 147gr ball and the rest Magtech 115gr ball, which I was shooting at the time. It has Talon grips and I was using an 8 round magazine and was firing from a two-handed isosceles stance.

I have field-stripped it and found that the extractor will hold a round and live rounds easily slide in and out of the chamber.

Is there anything else I can test or watch for to figure out what happened so I can decide whether this was a fluke or is a real problem?


PS: 40 points in 13.78 seconds for a hit factor of 2.9028 on Fluffy's Revenge 2 (CM 06-05)

I have about 200 rounds through my Shield and I had a few failures to extract. I am hoping that as the gun breaks in, it will do better. I don't think I had anything like that though. Mine were all the shell getting caught half way out. With my old XDs I had a ton of those like you had. With that said, I think most of my issues happened with crappy range ammo and when I swapped to some WWB, I only had one failure to extract. I now make notes through all my range trips until I can make sure I am issue free. I plan to go back to the range this weekend.

Yeah... Try something other than MagTech and see if you have any problems.
I prefer using Federal Champion (WalMart Maroon box) in my Shield at club matches. Other than needing more mag changes per stage, I'm still able to place in the upper third with my Shield.

It's not the ammo.

I dropped an Apex trigger kit and TruGlo sights on it last night and dropped everything in an ultrasonic cleaner during the process and lubed it well afterward. I took it to the range to zero it and test the trigger. I got three more FTEs with ~200 rounds of the Magtech, none with 100 rounds of Federal 115gr (RTP9115), and one with 100 rounds Blazer Brass 124gr (5201). I did notice a couple of times that the Magtech was being ejected over my head instead of to the right. This happened with multiple 8-rd mags and a 7-rd mag. I did keep two pieces of the failure brass and they show small marks on the rim.

BTW the takedown lever gets toasty when you start emptying mags.

I had the same issue with CCI blazer fmj 115 Alum case . I figured it was the ammo I wasn't happy when I bought it but at the time it was hard to find . 150 rounds three bad ejections ....
I was also having some issue with thumb and mag eject button too SO mine could have some operator issues attached !

Good to hear. :)

The new Federal aluminum ammo from Wally-world fails to reliably extract from my Shield, but all other ammo is A-OK.

I just stay away from the aluminum stuff now.

Ammo of choice

Pretty new as a gunowner but did a lot of research through forums as to which ammo for defense and/or the range.
I use only Blazer Brass FMJ when practicing and, if someone chooses to try to hurt me or my family, they are going to get a dose of Spear Gold Dots +P's.
The Blazer Brass shoots real well out of my 9mm Shield when at the range. Hardly ever a failure and my Shield normally looks reasonably clean afterward.
Everyone have a safe Memorial Day weekend, please!

Problem Solved

I shot off the remainder of the case through other pistols. I had one minor jam at the last match and a string of at least a half dozen failures to extract at the range yesterday!

I do not recall having issues with MagTech before and I was using a new gun, so I understand why I assumed it was the gun and didn't test the ammo.

MAGTECH fails to chamber

I recently took my new Sig sp2022 out for the first time. I had a box of Winchesters and a box of Magtech. The Magtech would often fail to chamber completely, sometimes on the initial slide close, other times in the second or third round in a magazine (after first one or two firing normally) I had at least one failure in each of five magazines. The Winchester had zero failure rate.

I ran my finger from the tip of the bullet down to the base and sure enough the Winchesters were much smoother, the Magtech had a bit of a lip where the bullet comes out of the case. They seem to be snagging when entering the chamber. It could also be that the sig is brand new and may snag less when broken-in, but in any case I won't be relying on Magtech anymore.
