Firearm with interchangeable calibers and/or improved sights

摘要

A replacement slide assembly for a pistol, the slide assembly having a barrel assembly with a barrel and a firing chamber. The barrel assembly also has a guide member which is a protrusion that extends horizontally outward from the barrel assembly. The replacement slide assembly also includes a housing with an interior wall that defines a groove that receives the guide member. The guide member and the groove in the housing are located forward of a firing pin assembly also mounted within the housing. The slide assembly or any firearm also includes an adjustable sight assembly that permits interchangeability between different types of sights without requiring that the firearm be re-sighted.

1. A slide assembly for a pistol having a frame and a trigger assembly of a first caliber comprising:
a barrel assembly with a firing chamber and a barrel defining an axis wherein the barrel assembly includes a lateral protrusion; and a slide housing that is adapted to be positioned on the frame of the pistol for reciprocation between a forward battery position and a rearward loading position, such that the recoil of the pistol induces the slide housing to slide backwards along the frame; wherein the slide housing defines a groove having a first section that extends in a direction parallel to the axis of the barrel; and the groove having an upper surface and a lower surface parallel to each other and closely receiving the protrusion therebetween when the slide is in the forward position, the rearward position, and all intermediate positions therebetween.
