The True Precision Threaded Barrel for Sig Sauer P365-FUSE is a drop-in ready 9mm upgrade designed for 4.3" P365-FUSE 9mm models. Built from USA-sourced certified 416R stainless steel, this approximately 4.95" overall threaded barrel does not retain the LCI cut-out and is made to outperform OEM standards. It is not for use with FUSE Comp slide pistols.
TRUE barrels use advanced cuts, chamfers, and an improved feed ramp designed for reliable feeding of all types of ammunition, including defensive ammo. Proprietary stainless steel broach-cut, 6-groove rifling with a 9mm 1:10 RH twist and a SAAMI spec 9x19 Luger chamber support accuracy and consistent performance. 1/2x28 muzzle threads include a high-heat integral O-ring lock thread protector. American-made precision, performance, and style.
NOTICE: This barrel does not retain the LCI cut-out. Pistols with a loaded chamber indicator require LCI removal or shortening for correct function with this barrel.
