Firearm

Abstract

A firearm comprises a chamber member, which is separate from the barrel and defines a chamber and which in a firing block, which is fixed to the receiver, is reciprocable between a firing position and a loading position in a direction which is transverse to the longitudinal direction of the barrel. When the chamber member is in its loading position its chamber is freely accessible and at one end communicates through a loading opening of the firing block with the interior of a magazine holder and at the other end communicates through an ejection opening of the firing block with an ejection shaft. For the performance of the loading and unloading operation, a slider is provided, which is movable in the longitudinal direction of the barrel and carries a feeder, which is movable from a first end position, in which the feeder is disposed on that side of the magazine holder which is opposite to the firing block, past said magazine holder toward the firing block as far as into the loading opening of said block. In order to ensure that the unloading operation will reliably be performed without a disturbance, the ejecting opening of the firing block has an edge portion which faces the chamber member when the latter is in its firing position and the firing block is provided in that edge portion with an ejecting nose, which is spaced from the inner edge of said edge portion and which merges into a deflecting surface, which is convexly curved from said inner edge to said nose, said nose protrudes as far as to the level of the adjacent inside surface of the chamber when the chamber member is in its loading position, and the movement of the chamber member from its loading position to its firing position is adapted to be initiated before the feeder reaches that end position in which the feeder extends into the loading opening.
