Help with Sig 229 please

[orangeninja]

I have a factory demo sig 229 that is accurate as any weapon I have ever seen. I love it. Shot it today for the first time. A slight problem with it however. The gun will not "combat load". Meaning if I shoot until slide lock, I insert a new mag and drop the slide, the bullet will not go into the chamber.....it sticks half way out. I have to pull the slide forward or rack the slide all the way back forcefully to get it to chamber that first round. No hiccups during the actual firing though.

Edit....forgot to say...the more I shoot it using factory S&B ammo the dirtier it gets. The dirtier it gets the worse the problem. The gun was freshly cleaned before I took it to the range and I only put 100 rounds through it.

Does anyone know what this is and how to fix it?

Do I need to take my gun to a smith?

Thanks.

1. check the mag springs to make sure they're not in backwards. Not enough spring on the front of the follower can cause this.

2. Check the insides of the mag's feed lips. *Maybe* excess drag there can cause what you are describing--I call it "nosedive" feeding.

Is this after the failure you describe? Or is it the only way to get it to feed the top round from a full mag?

Loading 16 in a 15-round mag can also cause this. Too much spring over the whole round and it drags on the feed lips when being fed. Dirty gun = dirty mag and can make it worse.

alduro,
Listen to what tuner has to say, the man is brilliant. His advice has helped countless shooters on THR. Try what he said, if it doesn't cure the problem,[which it most likely will], you might want to try something I learned from an armorer when I was in the Marine Corps. I was shooting a new .45 on the range and I was having trouble chambering rounds, similar to what your experiencing. The armorer came up to me and told me to put a drop of oil on the top round in the mag. What you do is put the oil on the round at the point where the bullet joins the case of the round. I did this and the weapon worked flawlessly. I continued to do this for the rest of the session without a mal of any kind. When I asked him how this made a differance, all he would say was ''don't ask''. I was a sgt, and he was an old salty m/gunny. I didn't ask. I never forgot this little trick, and have used it throughout the years, and it has never failed to work. You might want to try it. It doesn't cause any damage to the weapon, and once it's broken in you don't need to continue the oiling process. I've told this to other shooters with the same problem, especially in .22 cal auto loaders and it's worked for them as well.
good luck, and be safe.

Okay get this....I checked the ejector along side with my other 229....about the same in tension. I then cleaned it....though I didn't see much noticeable fouling....afterwhich I loaded a full magazine...(same mags) with 180 gr. Remington Golden Sabers. I droped the slied (not slingshot) and it fed every time. Not marks on the casings at all except where striped from the mag. The S&B bullets I believe have wider noses than the Remingtons but both are the same grain weight. I ususally use 155 gr. Winchester White box...maybe I'll put a couple 200 of those through it. It could have been the ammo?

I've never seen a Sig that was finicky about ammo.
