Wilson Combat Hammer Spring #19 Reduced Power 19 lb for 1911 Full-Size

The Wilson Combat Hammer Spring #19 is a reduced-power mainspring built for full-size 1911 pistols. It is tuned to deliver a lighter, smoother trigger pull without giving up the positive primer ignition the platform is known for. Rated at 19 lb, this is Wilson Combat's go-to reduced-power spring and is specifically intended for 9mm and .38 Super 1911 builds where a factory-rate spring is stiffer than the application demands.

Cut from steel with a natural silver finish, the #19 drops directly into the mainspring housing of any compatible 1911 frame. It is engineered to fit Wilson Combat frame letter designations A, B, E, F, H, N, and O - the families that cover the Government and Commander length slides. The reduced hammer tension takes the sting out of a heavy factory trigger while still reliably striking primers across a wide variety of loads, and the steel construction provides long service life in a working gun.

Whether you are dialing in a carry gun, refining a range 1911, or replacing a worn factory spring with a known-good Wilson Combat component, the #19 Reduced Power Hammer Spring delivers the lighter pull that serious 1911 shooters prefer without compromising function.
