PISTOL BARREL SYSTEM AND METHOD
First Claim
1. An interchangeable barrel system for a pistol comprising:
- an elongated barrel insert including a rear portion defining a chamber configured for holding a cartridge, and a forward muzzle portion having a bore defining a longitudinal axis and bullet pathway;
an elongated receiver fixedly mounted to a grip frame, the receiver remaining stationary during firing of the pistol, the receiver defining an internal cavity configured for axial insertion of the forward muzzle portion of the barrel insert into the receiver;
an anti-rotation device configured for preventing rotation of the barrel insert with respect to the receiver; and
a locking member configured for releasably engaging the barrel insert to secure the barrel insert to the receiver.

Abstract
An interchangeable barrel system and related method for a pistol includes a barrel insert having an anti-rotation protrusion and a receiver having a complementary configured socket configured for receiving the protrusion. An embodiment of a barrel insert includes a chamber for holding a cartridge and a locking mechanism configured for releasably securing the barrel insert to the receiver. In some embodiments, the locking mechanism comprises a threaded engagement between the barrel insert and receiver. The system allows barrel inserts of different calibers, configurations, and materials to be swapped with the receiver, and vice-versa.

12. An interchangeable barrel system for a pistol comprising:
-
an elongated barrel insert including a rear chamber block defining a chamber configured for holding a cartridge, a front muzzle end, and a forward muzzle portion extending between the muzzle end and the chamber block, the muzzle portion having a bore defining a longitudinal axis and a bullet pathway; an elongated receiver fixedly mounted to a grip frame, the receiver remaining stationary during firing of the pistol, the receiver defining an internal cavity aligned with the longitudinal axis and extending from a rear end to a forward end of the receiver, the muzzle portion of the barrel insert being insertable into and substantially disposed in the cavity; an anti-rotation device configured for preventing rotation of the barrel insert with respect to the receiver; and a locking member threadably engaging the barrel insert and securing the barrel insert in the receiver. - View Dependent Claims (13, 14, 15)
