I have a few 320s in 9mm, and decided to add a 45 to the stable.

Purchased a new stripped 45 FCU off GunBroker, now I’m just trying to confirm what 45 specific parts I need.

What I have so far:
FCU - Stripped
Compact 45 Slide - Complete - purchased from Sig
Compact 45 Barrel

I’m having a hard time figuring out if I need a 45 frame, or if they will all work....and then any other parts.

Any input is appreciated.

You need a 250/320 45acp grip and 45acp magazines.

Picked those up as well last night.

All the FCU parts (minus the FCU itself) are the same?

Im a little confused when you say minus the FCU itself. The FCU is a module that contains the hammer sear trigger/strker ect.In the P250 the FCU in all calibers is the same.I believe that to be true with the P320.

Thanks Trigger. I was under the impression, and definitely could be wrong, that there was a different FCU for the 45. The 9/357/40 could all use the same everything, but the 45 was different.

Again, could absolutely be wrong, trying to educate myself.

Guess I could pull out one of my 9mm and compare it to the new chasis when I pick it up from my FFL.
