One feature is the dual recoil spring system that spreads out the recoil force of the .45 ACP round by lowering the peak force of the recoil pulse. It also has 3-dot tritium night sights , a 5-inch national match barrel, ambidextrous safety, picatinny rail , and a desert tan Cerakote finish.
The standard recoil spring used in the Mark I and II pistols chambered for the .45 Winchester Magnum has a 27lb rating, compared to the 16lb rating for a standard M1911 pistol chambered for .45 ACP. The heavy spring, combined with the greater inertia of the massive slide, results in a manageable recoil impulse without resorting to the gas ...
Mainsprings can come in many shapes, such as a cylindrical spring (Mosin-Nagant, TT-33, Colt M1911), plate spring (Nagant revolver model 1895, Makarov pistol) or spiral spring (Kalashnikov). On a number of automatic firearms, the recoil spring may also function as a mainspring (FN Browning M1900, Degtyaryov machine gun, and some submachine guns).
The new 1911 was designated M45A1 or "Close Quarters Battle Pistol" CQBP. The M45A1 features a dual recoil spring assembly, Picatinny rails and is cerakoted tan in color. In 2019, the USMC selected the SIG Sauer M18 to replace the M45A1. [57] The Marines began the roll out of the M18 in 2020. [58] The replacement was completed by October 2022. [59]
Les Baer offers both his Baer 1911 Premier II 5" and Premier II Super-Tac pistols either in .400 Corbon or as a .400 Corbon and .45 ACP dual caliber combination. [ 26 ] Nearly any .45 ACP pistol can be converted to utilize the .400 Cor-Bon cartridge with only a drop-in replacement barrel , and sometimes a heavier recoil spring (for 1911s this ...
The .45 ACP "Colt Commander Gold Cup" was designed to offer competition-ready out-of-the-box performance in National Match competition. It came with one 8-round magazine plus a separate recoil spring and one 7-round magazine for wadcutter ammunition. [3] The "Colt Combat Elite" was specialized for combat-style match shooters.
The Arsenal Firearms AF2011-A1 is a double-barreled, semi-automatic pistol of Italian origin. The weapon is a derivative of the M1911 pistol and the majority of internal parts including the firing pins, firing pin plates, sear groups, springs, recoil rods, and mainspring housings are interchangeable with standard M1911 replacement parts.

The simplest form of recoil buffer is made from a resilient and deformable material (leather, rubber, polymer e.g. a rubber butt pad on a shotgun). [1] A second way of producing a recoil buffer is to insert a spring into the recoil train—the path/part(s) generating recoil impulse.
