Ed Brown 1911 Bobtail Mainspring Housing
This beautiful skip line Bobtail Mainspring Housing by Ed Brown is a great upgrade for your 1911. Made from quality alloy steel featuring a secure plaid pattern for great grip engagement.
This part requires frame modification. We recommend that it be installed by a qualified Gunsmith using the Ed Brown #953 insulation jig.
Innovated and introduced by Ed Brown over 15 years 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. The Bobtail® uses an Officer’s model mainspring and internals, which are included and installed.
