Abstract: An adjustable recoil system is provided for an automatic firearm, such as a .45 caliber Colt automatic pistol, in which expanding gas from a discharged round propels a slide rearwardly on the pistol frame to eject a spent shell. The adjustable recoil apparatus is comprised of first and second recoil springs axially aligned with each other and compressed between the slide and the frame. The compressed recoil springs have different spring constants and are disposed coaxially about an elongated recoil spring guide that extends parallel to the pistol barrel. An annular recoil spring retainer is coupled to the recoil spring guide in coaxial disposition thereabout and is interposed between the first and second recoil springs. An adjustment screw is threadably engaged in the recoil spring guide and is coupled to the recoil spring retainer to adjust the longitudinal position of the spring retainer relative to the spring guide to vary the relative degree of compression of the first and second recoil springs.
