US12723826 - Recoil spring abutment for a slide of a modular handgun

A recoil spring abutment for a slide of a pistol, the slide including slide grooves on both sides, and the recoil spring abutment being designed to be insertable and mountable in the slide and includes a preferably essentially semi-cylindrical base body having at least partially continuous guide rails on both sides, and an essentially circular step on a rear side for accommodating a recoil spring assembly. The invention also relates to a modular slide for such a recoil spring abutment, as well as to a slide cover sleeve, which may be mounted on the slide by means of the latter, and to the slide cover sleeve itself.

The patent describes a recoil spring abutment designed for modular handguns, featuring a semi-cylindrical base body with guide rails that engage with slide grooves, allowing for easy installation and effective transmission of recoil forces. Additionally, it includes a circular step for accommodating a recoil spring assembly, enhancing the functionality of the slide without an integrally-formed abutment.

Claim 1

1 . A combination of a recoil spring abutment and a slide for a pistol, the pistol including a recoil spring assembly, the slide having no integrally-formed recoil spring abutment, and the slide having slide grooves on both sides of the slide; wherein the recoil spring abutment: includes a substantially semi-cylindrical base body having at least partially continuous guide rails on both sides of the base body; includes a substantially circular step on a rear side of the recoil spring abutment for receiving the recoil spring assembly; and is configured to be inserted and mounted in the slide by a coupling of the at least partially continuous guide rails with the slide grooves and urging the recoil spring abutment forward on the slide until the recoil spring abutment is in an installed state such that the recoil spring abutment is disposed beneath the slide and transmits recoil forces directly from the recoil spring assembly to the slide via the coupling of the guide rails of the recoil spring abutment with the slide grooves of the slide. includes a substantially semi-cylindrical base body having at least partially continuous guide rails on both sides of the base body; includes a substantially circular step on a rear side of the recoil spring abutment for receiving the recoil spring assembly; and is configured to be inserted and mounted in the slide by a coupling of the at least partially continuous guide rails with the slide grooves and urging the recoil spring abutment forward on the slide until the recoil spring abutment is in an installed state such that the recoil spring abutment is disposed beneath the slide and transmits recoil forces directly from the recoil spring assembly to the slide via the coupling of the guide rails of the recoil spring abutment with the slide grooves of the slide.
