Ed Brown 1911 barrels are manufactured in-house from T-416 modified stainless-steel bar stock produced specifically for firearm barrels. Government and Commander lengths are available in several calibers and feed-ramp configurations.
Manufactured in-house from T-416 stainless steel
Each barrel is machined from solid bar stock, stress relieved, and heat treated before final rifling and finishing. The barrels also receive sub-zero treatment for additional stress relief and dimensional stability.
Traditional six-groove rifling
The bore is precision broach rifled with six lands and grooves and a 1:16 left-hand twist based on John Browning’s original design. The traditional rifling can be used with jacketed or lead bullets.

Fitting and caliber compatibility
The bushing, barrel link, and link pin are included. These barrels are machined to drop-in tolerances, so machining is not normally required. Hand fitting is typically necessary and provides the best final barrel-to-slide fit.
A .45 ACP slide accepts the .45 ACP barrel. A .38 Super slide can accept either a .38 Super or 9mm barrel. A different magazine or recoil spring may be required when changing calibers, and the point of impact may change.
