Title: Springfield 10mm
Post by: triggerman10 on May 23 2019 08:05:07 PM MDT
Do the Springfield 10mm's have a 2 piece chamber? I have a lightweight bi-tone in 45acp that has the 2 piece chamber,always thought that was a llittle wierd. It's never been a problem,just didn't understand why.

I think he means like a traditional .45 ACP 1911.

The forum thread where that google image is sourced is from 2011, but as far as I know Springfield still does them this way.

Interesting, I assume it's mechanically fixed? IE the barrel is larger than the sleeve. Barrel is frozen sleeve is heated and fitted together. When they equalize temps it's seized in place.

I haven't seen this before but I have done the same thing with bearings and mega arms sbu billet uppers.

PM terdog

He got a TRP a while ago. From all my reading the 2 piece barrel was mainly used on gi models.

He should be able to look at his barrel and see a faint line indication g the two piece. But I bet they are all one on the 10mms they have released recently.

I've had my lightweight bitone for quite a few years now,it's not a gi model. Maybe they don't do it any more. I guess if i really must know I can email Springfield.
