Machined steel barrel bushings from ED BROWN are designed for a tight fit between the slide and barrel, specifically for the 1911 Commander model with a stainless steel finish.
The Drop-In version requires no fitting with Ed Brown Barrel and Colt slides, while other brands may need minor fitting. The Oversize version necessitates precision fitting for a match-grade installation.
Product specifications include a matte finish with dimensions for Drop-In at .581" I.D. and .699" O.D., while the Oversize has .575" I.D. and .705" O.D., with the Commander only available in Drop-In, stainless steel.
