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.
