The MEU is a modified M1911A1 .45 caliber pistol sometimes referred to as near match or combat accuratized. The MEU(SOC) Pistol is the designated backup weapon of Marines armed with the 9mm MP5-N Close Quarters Battle weapon. The M1911A1 was chosen for this role because of its inherent reliability and lethality, and because the MEU(SOC) modifications make the M1911A1 design more user friendly. The unique characteristics of the MEU(SOC) pistol are: commercial/competition grade ambidextrous safety, precision barrel, precise trigger, and rubber coated grips, rounded hammer spur, high profile combat sights, and an extra-wide grip safety for increased comfort and controllability (which aids in a quick follow-up second shot). The issue magazines are replaced with stainless steel competition-grade magazines with rounded plastic follower and extended floor plate. A solidly built pistol, this WE MEU replica is made completely of metal with a diamond textured rubberised grip, it feels very realistic in your hand. The blowback action is nice and smooth. This product is only compatible with gas designed specifically for Airsoft guns. Do not use lighter fluid or butane gas, as that will cause permanent damage.
