Questions & Answers
Will this 4.7 inch barrel work and fit in a P320 Carry 3.9 inch l know the barrel will be further out than the slide if it will fit work and operate Manufacturer Answer

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.

by Faxon Firearms, Manufacturer, July 16, 2025
Will this work with the Sig Pro-cut slide? Manufacturer Answer

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.

Faxon Barrel by Joel, Verified Owner, February 22, 2023
The barrel I got, had marks in it, and it was open. I ordered another and returned the 1st one. 2nd barrel was fine. Looks great. Shipping is very poor, this simple order and reorder, shipping took a long time.

Same as above by Matt, Verified Owner, October 20, 2021
Tin barrel is hanging up my procut slide, scratching the p00p out of top of barrel. Hopefully after few mags it scratches the paint off so it functions correctly.. Not to impressed so far. The barrel looks amazing though

I bought this as part of a custom 320 full size build. It dropped right into an aftermarket full size Slide and accepted a Guide Rod that used a 1911 Recoil Spring. All of this slid right on to a SIG Factory Fire Control Group and full size X5 Grip M...

From 8in groups to 4in groups by Clay, August 4, 2023
As several have stated I've experienced the barrel hood gawling after some use, though it functioned fine. I found no marks on the slide just the front top of the barrel. Maybe this barrel should be listed as may need fitting. The most important pa...
