The M45A1 CQBP or known as the MEU (SOC) pistol has a dual recoil spring system that helps spread out the recoil force of the . 45 ACP round making it easier to handle and this is done by lowering the peak force of the recoil pulse. This pistol has a 3-dot tritium night sights, a 5-inch national match barrel, ambidextrous safety, picatinny rail, and a desert tan Cerakote finish. Garand Thumb gives his thoughts on this pistol in this video and if you're looking for an airsoft version, Tokyo Marui makes one.
