DETAILED DESCRIPTION

[0029] The loading aid 100 according to the invention depicted in FIGS. 1 to 3, and likewise in FIGS. 4 to 7, is attached in the region of a rear end face 210 of the slide 200 of a firearm (FIG. 8), wherein a pin element (panel) 110, which projects beyond the lateral faces 220, 230 of the slide 200 with the two lateral regions 120, 130 lying opposite one another, is introduced into a horizontally oriented recess 211 in the rear end face 210 of the slide 200. The recess 211 is laterally and rearwardly open,

[0030] The two lateral regions 120, 130 of the pin element 110 lying opposite one another project beyond the lateral faces 220, 230 of the slide 200 (namely an aft/breech section of the slide aft of a breech face) in a symmetrically identical configuration.

[0031] The pin element 110 is configured as a plan-parallel panel, whereof at least one lateral region 120 projecting beyond the lateral faces 220, 230 of the slide 200 is oriented at a predefined angle of 45° to the main surfaces 1104 and 1105 of the pin element 110 which are plan-parallel (flat and parallel) to one another.

[0032] The two lateral regions 120, 130 of the pin element 110 configured as a panel project roughly 3 mm beyond a respective lateral face 220, 230 of the slide 200, wherein these lateral regions 120, 130 of the pin element 110 are provided with external grooving which comprises four groove edges in each case.

[0033] The pin element 110 configured as a panel is held within the recess 211 in the slide 200 in a form-fitted manner allowing lateral displacement, in such a manner that the longitudinal edges 1101, 1102 of the plan-parallel panel running parallel to one another are each provided with a step 1103, wherein the inner (forward) surface 1105 of the panel 110 has a greater height than the outer (aft) surface 1104 of the panel 110, in order to bring about a secure fit of the panel 110 within the recess 211, following a lateral introduction of the panel 110 into the correspondingly configured, horizontally oriented recess 211 in the rear end face 210 of the slide 200.

[0034] The horizontally oriented recess 211 in the rear end face 210 of the slide 200 is arranged in such a manner that the outer surface 1104 of the panel ends flat with respect to the rear end face 210 of the slide 200.

[0035] A recess 140 is formed in a central region of the inner surface 1105 of the panel, which recess is dimensioned for an introduction of a rear end face of a socket (spring cap) 150 in the region of a rear end of a firing pin spring 300 and biased in the direction of the recess 140, for the purpose of locking the panel 110 laterally within the rear end face 210 of the slide 200. The spring cap surrounds a rear end portion of the firing pin spring. The firing pin and spring extend with in a firing pin compartment in the breech section of the slide with a forward end of the firing pin extendable through the breech face when driven by the spring 300 for firing.

[0036] Depending on configuration, the spring 300 may act directly on the firing pin or may drive an inertial striker that impacts the firing pin. FIG. 7 shows an inertial striker in a forward/extended condition with relatively uncompressed spring 300 and a small gap between the firing pin rear end and a central projection of the panel; whereas FIG. 8 shows the inertial striker in a relatively rearward/retracted condition with the pin slightly further retracted under influence of a smaller firing pin return spring so that the rear end of the firing pin contacts the projection.

[0037] Two bores 141, 142 spaced at a predefined distance from the central longitudinal axis of the slide 200 are provided within the recess 140 at a predefined distance from the central longitudinal axis, which bores (holes) are dimensioned to allow compression of the spring 300 by means of a respective pin which is to be introduced. In particular, a pair of pins may pass through the bores to depress the spring cap and disengage the spring cap from the recess 140 to allow the panel 110 to be laterally slid out of the recess 211 (via cooperation of upper and lower rails of the panel in respective slots in the slide). Panel removal allows withdrawal of the firing pin assembly from the rear opening of a firing pin compartment previously closed by the panel. Firing pin and panel installation may be via the reverse.

[0038] The exemplary embodiment of the invention explained above serves simply to provide greater understanding of the inventive teaching embodied in the claims, which is not limited as such by the exemplary embodiment.
