We have not tested the full size 4.7" barrels in shorter Compact/Carry slides. While the locking dimensions are the same, the shorter slide will have the fluted section of the barrel resting in the muzzle of the slide. This could cause functional or accuracy issues.

Will this work with the Sig Pro-cut slide?

Yes, this should function with the 4.7" pro-cut slide. If the slide has a loaded chamber indicator this will need to be removed before the barrel drops in.

Does this for the p320 m18?

Manufacturer Answer
A
Answered by Faxon Firearms, Manufacturer from OH, United States, on September 16, 2021

No, these barrels will not drop in to the M17 or M18 variants of the P320 due to the Loaded chamber indicator present on those versions of the pistol. The loaded chamber indicator would need to be removed before our barrel would drop into the slide.
