FIRST question relates to holsters:
Will a P320C .45ACP properly fit in a holster for the P320C 9/40/357 models?

SECOND question relates to interchangeability of FCU (.45 versus 9/40/357):
Has been discussed here, but can't recall the details. IIRC, one will install in the other...but not the other way around. Please refresh my memory.

BACKGROUND:

Currently own a P320C 9mm (complete gun), P320FS .40 X-Change kit and a SC grip frame, all purchased from SigStore in early 2015. Bought a ton of mags and the X-Change shortly after the P320C 9mm. Made sense then, 20% off mags and the X-Change (before price went from 300 to 400). Have never had a single problem with reliability, accuracy, FCU or anything else. Perfect as is...still haven't sent it back for the voluntary "upgrade".

Now considering a P320C .45ACP. Hence the questions.

Thanks for any input.

Generally, no. But you may find the occasional 9/40/357 holster whose tolerances are loose enough to accommodate a .45.

.45 FCUs can be used with 9/40/357 grips/slides/mags. But 9/40/357 FCUs can't be used with .45 parts.

Exactly what I was looking for. Thanks Rogue.
