History

In the late 1980s, USMC Colonel Robert Young laid out a series of specifications and improvements to make Browning's design ready for 21st century combat, many of which have been included in MEU(SOC) pistol designs.

stated that "Marine armorers from the Precision Weapons Section, MCBQ" are making 789 MEU (SOC) 1911's. The revised parts list included barrels, bushings, link pins, sear springs, ejectors, firing pin stops, mainspring housings and mainsprings, all from Nowlin Manufacturing. Slides were ordered from Springfield Armory, with front sight pins, beavertail safeties and recoil spring guides came from Ed Brown. Novak was contracted for rear sights, Wilson Combat provided extractors and mag release buttons, while King's Gun Works supplied ambidextrous thumb safeties.

A Marine operator may shoot as many as 80,000 rounds from this pistol during a training-cycle and subsequent deployment. However, it is more common for a Marine to return the pistol to the PWS at Quantico for a rebuild after 10,000 rounds have been fired. A rebuild entails discarding almost all of the gun's parts except for the frame, which prior to 2003 was a U.S. Government frame last manufactured in 1945. The frame is inspected and reused again if it is still within military specifications. There are frames in the USMC inventory that have had as many as 500,000 rounds fired through them.

The Officer In Command of the Precision Weapons Shop in 2001, Chief Warrant Officer 5 Ken Davis, stated that the M1911 is "the only pistol that can stand up to this use".

However, as the U.S. Marine Corps began its process of hand selecting members from its Force Recon to be submitted to USSOCOM as Marine Corps Special Operations Command, Detachment One (MCSOCOM Det-1), the selection of a .45 ACP M1911A1-based pistol meant roughly 150 units would be needed, more quickly than the PWS could produce them, as PWS were already backlogged with producing DMRs

Kimber shortly began producing a limited number of what would be later termed the Interim Close Quarters Battle pistol (ICQB).

Replacement

Due to wear and tear of the MEU(SOC) pistols and increasing numbers of Marine personnel in Marine Force Recon and MARSOC, the U.S. Marines are looking commercially for replacements. Marine Corps Systems Command announced February 17, 2005, that it was going to purchase 150 Springfield Armory Professional Model pistols for use as MEU(SOC) pistols. This is the same pistol used by the Federal Bureau of Investigation

 SWAT and Hostage Rescue Teams; however, it had previously been rejected for adoption as the ICQB. Despite the planned purchase of the commercial pistols, Marine Corps Systems Command has continued to solicit parts to build additional MEU(SOC) pistols. In 2010, requirements were once more issued for an off-the-shelf system to replace the custom-built pistols. Three pistols have been offered to the USMC as a replacement for current M45 Pistols. Colt is offering their 01070RG (Rail Gun) pistol, which is derived from their existing XSE line of 1911-style pistols with a desert sand-colored surface treatment and Novak night sights. Springfield Armory is entering a variant of the full-sized Loaded MC Operator M1911A1 pistol with a military-standard 1913 rail, tritium night sights and finished with a two-tone black slide with an olive-drab green frame. The third entry from Karl Lippard Designs, a Colorado Springs-based arms maker, is called the Close Quarter Battle Pistol: an M1911A1-style pistol, built using S7 tool steel

 and a large number of proprietary components including accessory rail, grip safety, and sights.

Specifications

The original pistols were hand-selected standard government issued Colt M1911A1s that were gutted, deburred, and prepared for additional use by the USMC Precision Weapon Section (PWS) in Quantico, VA. They were then assembled with after-market grip safeties, a rounded hammer, ambidextrous thumb safeties, lighter triggers made by Videcki, improved high-visibility sights, accurized match-grade barrels made by Bar-Sto, Pachmayr rubber grips, front cocking-serrations, and improved stainless steel magazines made by Wilson Combat.

The trigger-pull weight is specified at between 4.5 and 5.0 pounds-force (20 and 22 newtons).

The pistol's components are hand-fitted and are not interchangeable. The last four digits of the weapon's serial number are stamped on the top of the barrel, on the right-side of slide assembly, inside of the beavertail grip safety, on each side of the ambidextrous thumb safety, and on the inside face of the mainspring housing group.
