Government Model Mainspring Housings
Ed Brown mainspring housings are fully machined from solid bar stock steel. No cheap castings or plastic is used. We offer a variety of treatments, including smooth, serrated, checkered, Skip-Line checkered, Snakeskin, Chainlink, and Chainlink II. The Government Model housing features drop-in installation in all full-size 1911 pistols including full size Para-Ordnance pistols such as the P-14 and P-16. All housings will work great with any finish or type of steel, including aluminum.

Bobtail® Housings
Innovated and introduced by Ed Brown over a decade ago, and widely copied by others in recent years, the Bobtail® is a concealed carry modification to your Government Model frame that transforms it into a Round-Butt pistol. It consists of a specially manufactured housing and frame modification. The Bobtail® removes a full ½" of excess metal from the bottom rear of the gun, where the mainspring housing pin is located. This not only reduces the weight, but solves two well-known problems of carrying a 1911. First, it drastically increases comfort during carry. There is no sharp butt to poke you in the ribs. Second, it increases concealment during carry, because the hardest thing to conceal on a 1911 style pistol has always been the sharp, projecting butt.
