Springfield Armory's 1911-M1 MIL-SPEC was designed to be like the original GI issue 1911-A1s. Springfield Armory also added its Integrated Locking System (I.L.S.) to the mainspring housing, which increases safety by allowing the operator to completely disable the handgun. It also features Cross Cannon Double Diamond Cocobolo grips, forged stainless steel matte rounds with polished flats for both the slide and frame, GI style recoil system, 3-dot sights, and a 5" match grade barrel.
