P220 slide length barrel compatibility

[shoengine]

I have a P220 and I have two barrels: the original and a threaded. The threaded was the longest one I could find, 4.9", but it doesn't protrude from the more than 1/8". Turns out it is only slightly longer than the stock barrel. I did some searching online, but there is very little info I could find on the various slide lengths and barrel lengths. I'm assuming I could get a slightly shorter slide, but I can't find longer barrels, and I can't really buy threaded in WA anymore anyway, so I think I'm stuck. Is there a way to find out what slide lengths are compatible with which barrel lengths?

What's the length of your barrel?

What thread pitch is the threaded barrel?

 

[Nosferatu]

Standard P220 .45ACP barrel length is 4.4".

P220 Carry barrel length is 3.9"

P220 10mm barrel length is 5"

 

[shoengine]

Not sure how to measure the length, but here they are side by side



Original barrel is marked .45 Auto, threaded is marked .45 ACP

What thread pitch is the threaded barrel?

I looked up the SKU and this is what I got:

Thread pitch: .578x28 TPI

It looks like you have a barrel for the carry.

Does the threaded barrel look like it measures 4.9"? I can't get either barrel to match up to measurements I've found online.

P220 threaded vs standard.

 

[jbett98]

A thread adapter made by a machinist/gunsmith to extend the barrel, or try to find one online.
I had Tornado Technologies extend my stock HK P9s 9mm barrel and you could barely see where the factory barrel met the threaded extension.

Haha, I do know it is too short to be operable, but I'm trying to figure out what I have and how to reconcile the barrel length I have for both of them. For instance, is this not a 4.9" barrel?

Doesn't look like it.

To further clarify, do you have the standard P220 in 45?

 

[roseburger]

Interesting, my threaded barrel is a touch over 5" from tip to breech.

Give me a little while and I will measure the std Nitron barrel, the std Carry barrel and the Tactical threaded barrels for a 227 (same length as 220 - got to dig it all out from the gun safe).

I have no idea. I got it about 10 years ago from my wife's dad when he passed, and I never found paperwork on it.

Your dust cover is definitely longer than my P220 Elite. Your stock barrel has the same measurements as my threaded barrel. I can't find anything on there being a long slide version other than the 10mm.

That appears to be a Super Match Two-Tone SAO… Nice! They have 5" barrels.

That is a really nice offer, thanks

He definitely has a non-standard P220 and the 4.9" barrel that he has is useless in that gun. You need to buy another P220 for that barrel.
