When a target pistol of the semi-automatic type is in use, the centre of mass migrates upwards as rounds are fired.
This causes a noticeable change in the recoil rotation which, in a high pressure competition, can mean losing significant points.
Today’s invention is a pistol of this type in which the magazine is driven out of the grip progressively, by a simple cam driven by the slide, as each bullet is fired.
The design maintains a fixed centre of mass, making behaviour of the gun more repeatable (especially in a rapid fire event).
