Suppressor setup
Ed Brown supplies the threaded barrel and does not sell suppressors. A Nielsen device—also called a booster, kicker, or linear inertial decoupler—is required for reliable operation with a suppressed 1911. Confirm suppressor compatibility and applicable requirements before purchase or use.
