Bar-Sto Precision 1911/2011 Commander 9mm Bull Barrel – Threaded & Extended for Compensator, Stainless Steel, Semi-Fit
Built for compact comp guns, this Bar-Sto Precision 9mm bull barrel is extended and threaded .686x40 so you can mount a compensator on your 4.25" Commander-length 1911 or 2011. Bar-Sto has long been a trusted name in match-grade barrels, and this setup gives builders a precise, consistent foundation for a shorter, faster-handling comp pistol.
The bull barrel profile eliminates the traditional barrel bushing and adds mass up front, and paired with a compensator it helps keep the muzzle flat and the dot or sights tracking for fast, repeatable follow-up shots. A great choice for shooters who want comp-gun performance in a quicker-pointing package.
Available in two ramp cut options to match your frame:
- Para/Clark
- Wilson/Nowlin
Be sure to select the ramp cut that matches your frame before ordering.
Machined from stainless steel for durability and corrosion resistance, this barrel is semi-fit and will require minor fitting for proper lockup and function. Compensator not included; confirm your comp uses .686x40 threads before ordering. Installation and comp timing by a qualified gunsmith is recommended.
