Sig threaded barrel does not fit in P220 or in P220 Combat BBL-220-45-T

Hello all. I've been a long time reader but never a poster. Today I have cause to create a post!

I have a P220 that I've used since the late 1990s (best pistol I've ever fired!) and I recently picked up a P220 Combat.

I ordered a "BBL-220-45-T" so I could have a threaded barrel option for either pistol if ever I should decide I want a suppressor.

The barrel does not assemble into either pistol. It fits into the upper just fine, but when I slide the lower on, I can get it almost all the way on, but it catches... I think on the most downward protruding item on the barrel (can't remember what it is called).

http://pics.livejournal.com/larvatus/pic/001wc8z9

In that pic ^ ^ Whatever that rightmost tip is called.

I'm ensuring the bolt is pressed cleanly into the upper and seated into the ejection port properly. Reassembling both pistols with their original parts results in no issues. I have a long history with Sig pistols and I can't imagine the problem is with me... but I'll never say never.

***? I'd not expect something like this from a $200+ accessory for a $1,000+ pistol.

Any ideas what is wrong?

new slide or frame could be a little different from late '90's 220.

not my pic but a 220 sport barrel in a 220 frame, poster said it had no problems.

Also a long time reader but never a poster. I recently experienced the same issue with a 226 mk25. 95% probability it's the barrel.
Call Sig and they'll explain it to you. Two options, return the barrel and wait for a supply of new barrels or send in your gun and barrel and they'll make it fit. But of course, I'd much rather you hear it from Sig. I've been impressed with their customer service.

Here's my 2 cents worth - All is not lost, yet.

The Bar-Sto site has how to fit their barrels under FAQ's but here is the gist of it. Be sure that the barrel Hood fits into the slide first. This is very important because you would like the barrel bushings that are cut in the slide right under the front sight to be a tight fit. If the barrel is not up high enough into the slide you will be able to rotate the barrel by a tiny amount. This would mean that the bushings are not grabbing the barrel. Usually then you would need to take a small amount of material off the rear of the barrel where it touches the breech. (usually the highest part that touches the breech)

After you are happy that the barrel is just like you like it in the slide , then and only then can you remove material from under the feed ramp. Now, do you see what I mean about fitting the barrel to the slide first? If you take material off the bottom of the feed ramp first and then need to move the barrel up into the slide more you will not get good barrel lock up into the pistol.



So, what is happening right now is the bottom of the feed ramp is hitting the Locking Insert. Really that may be good because if it were the other way around and there were too much slack then the barrel would not lock up and be accurate.

Just be sure and be happy that the barrel in up in the slide where you want it and then remove a very little bit off the bottom of the feed ramp and try to put the pistol back together. Keep taking a tiny bit more off and check again. It should not take much.

Be sure that something else is not keeping the slide going on like the Take Down Lever turned the wrong way. It should be turned down.

(so fjgiie, how do i take a little off the bottom of the feed ramp? i like to use 2000 grit wet or dry paper and light oil - i fold the sandpaper around a small steel ruler and sand parallel with the bore)

Don't Do This When Tired

That was worth more than two cents. You have hit the nail on the head on what the problem is and how to fix it yourself. If SigDude feels comfortable with that fix, go for it. We both purchased new barrels and I for one am hesitant to start grinding on a $200 barrel.

Sig is aware of the recent barrel issue and represented to me that they would make it right. Since barrels are out of stock for another estimated 4-6 weeks, I sent my firearm and new barrel in for a custom fit and was assured the minor grinding would have no long term effects. (I was concerned about rust.)

Thank you all for the replies!

I will closely evaluate fjgiie's remarks alongside the pieces in question and see what is to be seen.
