i have a few 1911's
all run flawlessly, except for the Springfield RO Elite Target. at first it wouldn't go completely into battery about 1 out of 20 shots, almost into battery but not quite. i changed to a slightly heavier recoil spring and now it runs fine. could have been needed more break in rounds bc the slide was super hard to rack at first, after a few hundred rounds it has loosened up some but its still tight.
my Springfield Long Beach Operator is the best I have. its essentially a Loaded Operator. i can't afford the full custom 1911 that runs$3-5k, so i went with the best that i could afford. slide is tight too, the only 1911 i have to use the bushing wrench to take it apart. but from the get go it has been great, no hiccups, very accurate, trigger is very crisp, sights are great, its a pleasure to shoot. this is my best semiauto pistol.
you could spend a lot more for something custom if that's what you are looking for, but for me this works very well. its more accurate than i can shoot and it is ultra reliable
