All Infinity magazine releases are billet machined from 416 Stainless or 4140 Chrome Moly steel and heat treated to Rc42. All Infinity components are machined to exact tolerances for a better first-time fit and the inherent strength and hardness to last the life of the pistol.
These 1911 magazine releases are available with a raised shelf to help correct bullet feeding issues in some pistols. The raised shelf allows for the magazine to be held higher in the gun.
Installation is suggested to be completed by a competent gunsmith.
