AB Prototype A-10 Threaded Barrel for SIG Sauer P320, 10mm, 5.7", no LCI, Gold PVD (TiN), .578"-28
This is a new AB Prototype A-10 threaded barrel for the SIG Sauer P320 X-TEN in 10mm AUTO. This precision machined barrel is cut from 416 stainless steel and threaded .578"-28 (standard .45 thread). 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/.40 full-size (4.7" or 5.0") slides. Drop-in fit for reliability.
The .578"-28 thread is the standard thread for most .45ACP pistol accessories, i.e. suppressors, comps, thread protectors, etc. Our threaded barrels will allow compatibility with most 45 barrel accessories on the market.
Included with our threaded barrels is our thread protector comp. This muzzle device will add a bit of style and performance to your threaded pistol. Six flats make for easy installation. Manufactured in the USA from 1144 Cold Drawn Alloy Steel and Black Nitride (QPQ) coated for improved wear-resistance. Thru bore is .470".
Please note this barrel will not fit X5s and similar P320s in 9mm, .40 or .357SIG. THREADED BARRELS ARE NOT LEGAL IN ALL STATES. Please be aware of state laws before ordering/installing.
