摘要

The process for eliminating the critical multidirectional play between the barrel 1 and the carriage block and other parts of automatic pistols, at least those with closure, comprises the provision between barrel 1 and carriage block 2 of an interface 3, 03, 3' in the form of a tapering coupling, with a shim which can be adjusted at least once, where the concave coupling member 23, 23' is fitted on the muzzle of the carriage block and the tapering convex member 32, 32' is located on the muzzle of barrel 1. Preferably the tapering portions 23, 32 of the coupling are spherical and the radius of the sphere is such as to provide a coupling between the concave spherical strip 23 and the convex spherical strip 32 using a portion of a sphere whose median circumference has a tangent of 45 degrees.
