sig 226 not reliable w/ corbon 115 gr +p 9mm

The sig is reliable otherwise. The round will catch at the base of the feed ramp approx. 1 in 30 rounds. This round is shorter than others. Does the gun need to be sent to sig arms, or should I just use other ammo?
This is a late 1980's sig. The plastic grips have warped out slightly at the upper rear at the points.
Has anyone else had these problems?
 
I would never run Cor-Bon ammo through my precious SIG's. That is like letting your daughter be an intern for Clinton. Try Federal Hydra-Shok 135gr for fast, effective relief.
 
Simply switch ammo.

Not all loads work in all guns. This is normal and not particularly a 'gun problem'.

You have discovered the reason gun writers recommend firing 500 rounds of your chosen carry load before depending on it..........

What???? a sig that wont take everything you feed it??? According to most, only glocks do that right???? Ah, must be the ammo, couldn't possibly be Sig, huh??
 
Is ya crazy?

Cor Bon has been widely known to have some serious consistency and quality problems with their ammo. Why don't you just try shooting some Triton Quik Shok pre-frags in there while you're doing the nasty to your gun?

In all sincerity, it's probably the ammo and not your Sig.

Although polishing the feed ramp with some Flitz metal polish sounds in order.

Cor Bon is too darn hot.

Polish your feed ramp, take two 124 HydraShoks and go to the range tomorrow.

Too hot? Nahhh. I respectfully disagree. The head supervisor of SigArms service shop himself told me that +p ammo in the 9mm Sigs, and he specifically added "225" since that was my concern at the time is A-OK. ;) This was not an official policy of the company that you will find in writting. However, his opinion was that the 225 was made plenty strong enough to stand up to +p factory ammo. He indicated that any of the line can handle +p ammo. That said, the hotter the ammo, the quicker the wear. I doubt if our friend has the money to wear out his Sig any time soon by shooting Corbon ammo. If he does, he can afford to buy a couple of extra Sigs as they wear out. Hotter ammo, though does affect timing, and can cause certain failure to feed problems, especially in guns w/tired springs.

Rover,

You mentioned that the round that is getting hung up is shorter than the others. This DOES sound like it may be an ammo defect. If this is the case....the case might be approaching or exeeding safe pressure levels for any handgun of any make if the bullets are seated too deep. I would contact Corbon about this. Do NOT shoot any more of that stuff through anything! They should be willing to exchange the inconsistant box w/a new one. If you don't want to use Corbon any more, they should be willing to (or the gun shop that you purchased it from) refund the cost w/a sales receipt.

Q: Have you changed your magazine and recoil springs lately? If its been a few thousand rounds since a new factory spring for each, or if you leave your mags loaded, it may be a contributing factor to your problem. Maybe not THE reason, but a part of the reason for your hang ups.

For example: A weak recoil spring or a weak mag spring will affect your timing. The time it takes for the slide to eject a round will
decrease with a weak recoil spring. The time it takes for a round to slide up the ramp into the chamber will increase w/a weak mag spring. With this problem can lead to the slide returning at such a velocity w/+p ammo that the new round doesn't have time to get into position.

If your round is getting stuck at the BOTTOM of the ramp, its probably due to the combination of a cartridge length under specs and a weak mag spring. Polishing the feed ramp MIGHT help, but it sounds more like a weak spring. Especially since, I presume, its been feeding OK since the 1080s.

I hope that this helps.

Sig said to replace the recoil spring every 5000 rounds. If that doesn't work, ship the gun to them. They said it is out of warranty. It is completely stock & has certainly had more than 5000 rounds put through it. Sig sent me a free set of grips. They responded quickly to my fax. I have been impressed with their customer service.
 
Rover,

Glad to hear SIG Arms has lived up to its excellent reputation for customer service. Did they send you a free recoil spring as well?

fyrfytrj,

What's the point of your post?

Equalizer,

Thanks for the information.

So many pistols, so little money.
 
My understanding is that some SEAL units use custom loaded +P+ 9mm in their 226's, with outstanding results. Of course, if they break/wear out, Uncle Sam buys 'em new ones! Wouldn't it be nice if we could dsesignate that some of our hard-earned tax dollars were spent on personal defense... a new SIG for everyone on TFL! ;)
 
No, they didn't send a free recoil spring, but the gun is over 10 years old, thats fair. Since I'm going to be buying parts from Sig, what else should I get as a parts kit? Maybe new mag springs, an extracter & a firing pin? Is Sig the best source or a Sig distributer? Is it time to have the gun detail stripped & cleaned? Should anything be modified other than polishing the feed ramp? Any suggestions wuld be appreciated.

Equalizer-it looks like you were right about the recoil spring. I think the corbon 115 gr is just made shorter than most 9mms.
 
Rover,

Did you mean that ALL of the Corbon ammo is shorter than competing brands, or that there are some rounds of Corbon 115 that are shorter than others in the same box? Even w/the aggressive hollowpoint of the 115s, I would be very surprised if the problem was the profile of the round. Although I've run different types of 9mm ammo through the same magazine and shooting string at times as comparison, I've yet to ever experience hang ups.

In addition to the recoil spring, I'd definitely replace the magazine springs. They do take some set and weaken a bit over time if they are stored full. The Sig factory springs are fine. But one more possible source for magazine and recoil springs is "Wolff Springs." gunsprings.com/SemiAuto/SigArmsNF.html#226Magazine They have one of the best reputations out there. They also make some 10% over factory increased, (standard too), mag springs. Its easy enough to replace the springs yourself. If you need some directions just check back and I will be glad to walk you through it. No need to send it out for that job.

I've run literally thousands of reloaded rounds through my Sigs, using 9mm Sierra 115gn and 124gn hollow points, just like the ones used in CorBons. Never any trouble, but then again, I load with a COL a little longer than CorBon factory ammo. For safety's sake, since their 115gn +P stuff is loaded so close to tolerance, they heel crimp to help prevent set back problems, which could lead to overpressure problems. I don't like CorBon stuff because of inconsistencies in velocity, I've clocked over 800fps differences in one box!!! But I've never had a problem with set back on their rounds, good crimps on their part. NOT GOOD STUFF in my experience, so I use HydraShoks and Golden Sabers.
