The Brownells Single 1911 Rail Swage Punch applies downward swaging pressure directly onto the frame rails and not on the frame. Giant steel punches with specially machined steps prevent overpeening and crushed frame rails. This precision tool measures 5-7/8″ long with a 1″ diameter, delivering professional-grade gunsmithing capability for serious 1911 work.
By putting downward pressure directly onto the frame rails rather than the frame itself, and with single design allowing tightening of specific rail areas, this punch enables a closer frame-to-slide fit essential for accuracy and reliability. Manufactured from machined steel, the Brownells Single Swage Punch is built to handle the demanding requirements of proper rail forming and seating on Government, Commander, and Officers model 1911 platforms. Whether you’re a professional gunsmith or dedicated enthusiast, this punch is a must-have tool for precision 1911 frame rail work.
