The Marines chose to stick with the 1911 design for MARSOC. Marine testers placed a high priority on accuracy. The winner of the 2012 contract had to be capable of putting five-shot groups on target that "didn't exceed four inches by four inches at 25 yards" from an unsupported firing position, Marine officials maintain.
But military pistol experts maintain that the 1911 design, while extremely accurate, requires more training and care than other modern tactical pistols.
Young operators have had trouble with the 1911's beavertail grip safety, according to one former Marine weapons instructor who trained MARSOC members.
Many shooters wearing gloves tend to grip the 1911 too high and do not properly disengage the beavertail grip safety, so the pistol won't fire, he said. A lot of professional shooters who run custom 1911s will disable that beavertail grip safety to avoid this problem, he added.
The 1911 design is also known for feed-way stoppages, a malfunction caused when a round gets stuck feeding into the chamber, experts said. Horizontal and vertical stovepipes – types of malfunctions that occur when an empty shell casing gets caught in the ejection port – are also a problem with the 1911 design.
