The Ed Brown Bobtail® 1911 mainspring housing is the central component of the carry modification invented and introduced by Ed Brown. It converts the projecting lower corner of a Government-size 1911 frame into a rounded-butt profile.
Designed for carry and concealment
The completed Bobtail® modification removes approximately one-half inch from the lower rear corner of the pistol. Rounding this area eliminates the sharp corner that can press against the body and reduces the portion of the grip most likely to print beneath clothing.
Housing and internals included
The Bobtail® uses an Officer-size mainspring and related internals. These components are included and installed in the housing.

Professional frame modification is required

Review the Bobtail® jig and installation instructions before beginning the conversion.
