Sorry but that has to be the dumbest military procurement error since the Chauchat. Top of my head I can come up with the Glock 21 and the FNX 45 as far more reliable, lighter and bigger capacity handguns that would serve the Marines much better than a 1911.
The tradition says that the jarheads always get stuck with the crappy weaponry. Apparently tradition is right. At least they did not go for the S&W Model 10 revolver, Thank God for small favors.
