ABSTRACT:
A method and a device for retrofitting existing autoloading pistols having a one-piece bolt stop pin. The first step of the retrofitting method is to cut off the original bolt stop pin and then machine a threaded bore in the remaining shaft. In addition, an extension which mimicks the original bolt stop pin configuration is manufactured. The extension has a threaded end which is screwed into the threaded bore in the remaining shaft portion of the original bolt stop pin. To disassemble a pistol having a two-piece bolt stop pin, the bolt stop pin extension is unthreaded from the remaining shaft portion using a screwdriver or similar implement. Then the loose extension is pulled upwards and out of the receiver, freeing the bolt to be pulled rearward and out of the receiver. The pistol is further modified by rounding the sharp upper corner of the hammer, e.g., by machining a smooth radius. As a result of this modification, when the leading edge of the reinserted bolt contacts the rounded upper corner, the hammer will be cammed downward and out of the way as the bolt is reinserted. When the bolt is fully inserted, the bolt stop pin extension can be screwed back into the remaining shaft portion of the original bolt stop pin, thus locking the bolt to the pistol.
