Compact 1911's have always had reliability issues.
Specifically, the ability to fire, extract & eject the fired case and then load the next round into the chamber.
It revolves around the slide being too short in amount of travel within its extraction/feed cycle in balance with too much spring trying to assure the reload part of the cycle while functioning in the full rearward position in the cycle.
Ammo is the main problem. You MUST fire multiple mags of the actual ammo you are going to carry for duty/protection to assure reliability.
Firing FMJ practice rounds to break in the pistol is OK...but has a different cyclic function that JHP rounds due to velocity and operating pressures of the rounds which change the slide velocity in cycling.
A commander length slide or full size 1911 has much more reliability.
