Sig P226 Failure to Feed?

[LooseGrouper]

I have a Sig P226 that was a police trade-in. I'm sure it's seen plenty of rounds, but it has never missed a beat until today.

I took it to the range and had six or eight failures to feed out of about 150 rounds. These weren't "hard" failures, as a 1/4 re-rack or a little tap on the back of the slide would send it into battery. Various types of ammo gave the same problem (Fiochi 115, Win Silver Tip 115, Fed Hydrashock +P+ 124). I was able to repeat the problem at home only by slowly cycling the slide manually. I think the edge of the case mouth may be catching on the block at the top/rear of the barrel (the cartridge is parellel with the barrel when it "sticks"). Here are my questions.

1) Anyone have similar problems? How worried should I be about this?

2) Is it feasible that the mouth of the case is catching as I theorized? If so, can the rim of that block (don't know it's name) be safely radiused to prevent it?

I've had horrible luck with handguns of late. If I don't get this sorted out, I'm gonna be down to a S&W .22 for defensive carry (unless someone can tell me how to fit an 870 into a glove box...).

I don't shoot my Sigs much because I don't like DA/SA, but for my 1911s and other guns when this develops in a gun that had been working fine it tells me:

1) Time to clean it, don't forget about cleaning the mags too.

2) If cleaning doesn't do the trick, probably time to replace recoil spring. But I'd try a different mag first if I had one that I knew was good as weak mag springs or dirty mags can also cause feed problems. Also mag might have gotten damaged somehow in a previous session.


Slowly cycling rarely tells you anything useful -- weak mag springs are fine on a longer time scale of cycling. The dynamics of the cartridge mag feed lips and spring lift as it clears the feed lips are what makes it feed right or not assuming the frame/barrel wasn't out of spec from the git-go.

again. The malfunction you describe does indeed seem to be "crud related".
