I used the same old clapped-out 1911A1s in Germany in 86-88 and still managed to shoot expert, even though on one range I happened to notice a magazine floorplate, spring, and five rounds of ammo spilling out onto my feet. I still contend that the only problem with the 1911A1 was that the most RECENT military contract for new production was 1945. My "new" Springfield Armory and Norinco 1911A1 clones have been chugging along steadily for years now.
My contention is that if a pistol ain't really that important in the sceme of things and is chambered for 9mm anyway, one could have adopted something the size and weight of a Makarov or a H&K P-7, instead of something as big, heavy, and clunky as the "obsolete" 1911A1.
With my roommate being company armor 88-90 at Ft. Knox, He had to keep track of the rounds put through the then new M-9s. First, he had to send them in to be checked for stress cracks in the slide every 5,000 rounds and this limit was later dropped to 3,000. In 1989, the Army Chief of Staff's Office in the form of General Carl Vuono, sent the chairman of Beretta a letter putting the company on notice for a possible cancellation of the contract because the slide problem had not been fixed.
Maybe I'm just a malcontent, but when I buy a brand new pistol, I quite naturally expect the damn thing to last a lifetime.
