Abstract
An automatic pistol is constructed with a more or less conventional frame and more or less conventional barrel detachably mounted to the frame. The frame and barrel have interfitting portions in cooperative engagement to support the barrel in longitudinal alignment on the frame. The frame is provided with a seating surface for the bottom of the barrel, an abutment surface against which the breech end of the barrel abuts, and a well, forward of the abutment surface, into which a barrel block loosely fits. The barrel block is attached to depend from the barrel. A longitudinal bore through the barrel block partially registers with a corresponding threaded bore through the frame forward of the barrel block. The forward opening of the bore in the barrel block is countersunk, and the axis of this bore is slightly above the axis of the threaded bore with respect to the axis of the barrel. A screw with a tapered end is threaded through the threaded bore to engage the barrel block bore, thereby urging the barrel down onto the seating surfaces and back toward the abutment surface of the frame.
