Benjamin Perez, member, from WI, United States, asked on July 10, 2022

What barrel do I need for the 3.6 slide. first time building one up

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on July 26, 2022

The Faxon Firearms Sig Sauer P320 Compact Flame Fluted/Threaded barrels are Not compatible with X-Carry or X-Compact models or slides with a Tactile Loaded Chamber Indicator (Including the M18 variant slides). The standard Sig P320 Compact has a 3.9" barrel. To find a compatible barrel you would need to know the specific model P320 you have. If it is the P320 XCompact with the 3.6" barrel, the barrel at the link below will work.

Will this fit my P230 3.9 Xcompact spectre?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on March 07, 2022

The Faxon Firearms Sig Sauer P320 Compact Flame Fluted/Threaded 9mm Barrel will not fit your Xcompact as Faxon barrels are not compatible with X-series pistols. I would recommend the ZEV Technologies XCompact PRO Barrel that is compatible with your Sig. You can find it using the following link.
