Abstract

A barrel bushing for a semi-automatic pistol. The barrel bushing defines a bore for receiving a barrel therein for reciprocating movement during operation of the pistol. The improvement to the barrel bushing comprises first, second and third annular bearing surfaces formed on inner walls of the bore and against which the barrel moves during operation of the pistol. The first bearing surface contacts and supports the barrel during the recoil phase of operation, and defines a plane parallel to the longitudinal axis of the barrel during recoil. The second and third bearing surfaces reside in axially spaced-apart relation on opposite axially-extending sides of the first bearing surface and define respective planes with respect to the first bearing surface which are parallel to the longitudinal axis of the barrel during lockup and on which opposite upper and lower surfaces of the barrel are supported during lockup. A method of manufacturing the barrel bushing is also disclosed.
