AB Prototype A-10 Barrel for SIG Sauer P320, 10mm, 5.0", no LCI, Gold PVD (TiN)
This is a new AB Prototype A-10 barrel for the SIG Sauer P320 in 10mm AUTO. This precision machined barrel is cut from 416 stainless steel. Tighter-than-factory tolerances, but still a direct replacement barrel for the SIG Sauer P320 X-10. Will work with the P320 X-TEN models in 10mm only or for a custom 10mm P320 build. Also works with aftermarket XTEN (X10) slides, AB Prototype and others. Will not work with X5, M17 or other 9mm full-size (4.7") slides. Drop-in fit for reliability.
Please note this barrel will not fit X5s and similar P320s in 9mm, .40 or .357SIG.
Includes: 1 AB Prototype A-10 5.0" Barrel, 10mm (NO LCI CUT), Gold. Factory grease may be present. No other parts are included.
Installation is available for an additional charge.
