I just got a new 226 Blackwater. When shooting the slide doesn't lock back on an empty mag. It locks back fine when you pull the slide back by hand on an empty mag. None of the 5 mags that came with it worked. Ammo was 115 gr. FMJ Magtech. Has anyone else had this problem? I only put 100 rounds through it today, will it break in and start working or does it need to be fixed? Is this something I can adjust or does it need to go back into Sig for work? Thanks for any help you guys can give me Rick Edit to add - pistol was field stripped, cleaned and oiled before shooting. |
| It sounds like your recoil springs It could also be the magazine springs but since you can pull the slide back by hand and all mags lock it open it sounds like a weak or tight recoil spring. I would suggest you put another 500rds through it and included some hot ammo like Corbon and see if the slide locks back then. |

Thanks for the reply. I'll try out some other ammo tomorrow and see if it helps. I think I might have been riding my thumb on top of the slide release lever while shooting. I usually shoot 1911s so I'm used to my thumb being on top of the thumb safety so it was probabily operator error. Rick |

I'll bet that this issue is being caused exclusively by your thumb riding the slide release. I've had to overcome this with my new Sig P226 Navy. I confirmed that this was the issue by shooting weak-handed (I'm a righty) for a few mags, and guess what, no more issues with the slide failing to lock back. Coming from H&K's and Beretta's, I've had to adjust my grip a tad to accomodate the P226's uniquely positioned slide release. Instead of resting my primary hand's thumb snugly along the frame (as I normally do), I've learned to place this thumb slightly off the frame and more on top of my support hand's thumb. Kind of tricky to explain, but if you grip the pistol with a tight/high, thumbs-forward grip you'll see what I mean. While I generally like the ergos of the Sig, the placement of the slide release is a bit unique. |

...that's what I'm sayin' too...I have been shooting 1911s for a while now and recently took out a P series (P225) to the range...I don't do exactly the same problem you describe being a SouthPaw but I had to make an adjustment...let us know if this fixed it (bet it does) cuz your Sig should run like a top Bill |

The thumb used to be my culprit, but also the slide lock spring can be too stiff. The slide moves much quicker during actual firing than when you manually retract the slide. Some Sig owners have replaced that spring. What I did with my 220 was to manually push up and down on the slide lock while watching TV. Also, I took apart the Sig, and put an empty mag in the frame, which pushed up on the slide lock. You can even pry it up further by pushing a toothpick in there, and leaving it for a few days. That improved my 220. My 228, 229 and 230 have never had this problem. |

Here is one more thing to consider. My SIG 226 Navy came with the wrong slide catch lever installed. The end piece is shorter for a .40 than a 9mm. I tried the one from my 228 and instantly fixed the problem. If you have other SIGs like a 229 or 228 you can try switching this part to see if that is the problem. The part you want is SIG SKU 34260120. I just ordered a replacement from www.topgunsupply.com and installed it myself. My gun now runs like a top. You can call SIG customer service and talk to them or send the gun back as well. This is a fixable problem once you see what the problem actually is. IM or email me if you need more detail. Good luck mate. |

Thanks for all the ideas. I'm hoping to hit the range in the next couple days and pay extra attention to my grip to see if it is whats wrong. I'm going to run a bunch of different ammo through it too. I'm 95% sure its just my grip but if the slides still not locking back i'll take a look at the slide catch. I'll post an update after the next trip. Thanks again Rick |
