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 Taurus PT1911 is a replication of the US military model 1911 single-action recoil operated semi-automatic pistol.Designed in Porto Alegre, Brazil, it was initially distributed and released in the U.S. consumer market in the fall of 2005.
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]
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 ...
RIA (Rock Island Armory) 1911s are derivatives of the US Military G.I. M1911-A1, the standard issue US Service pistol from 1911 to 1985. [3] Most RIA models are targeted at the low-end price point of the 1911 pistol market and are basic entry-level MIL-SPEC versions of the 1911.

Since the spring can only be compressed a certain amount, this limits the amount of force the spring can absorb, and provides an inherent level of self-regulation to the action, allowing a wide range of shotshells to be used, from standard to magnum loads, as long as they provide the minimum recoil level to compress the spring. Note that the ...
