I think this whole question is overdone. Modern quality 1911’s built by reputable companies just don’t really have reliability issues anymore when properly maintained. I have several but the four I’ve shot the most over the past 5 years or so are a Wilson CQB, a Les Baer CC, a Springfield MC Operator, and a Springfield Long Beach Operator. The LB Operator is my work/do it all gun. It’s been through classes, bad weather exposure, a bunch of stuff. All guns are run primarily with Wilson ETM mags but an occasional Mecgar will slip in. Training Ammo is pretty much American Eagle 230 grain and operational is Federal 230 grain HST. None of the four of them have ever failed to go through their full functional cycle, with the exception of a couple failures to lock back that were traced back to an aging Wilson 47D that slipped into the rotation. I don’t know what better performance I could expect and aim certainly not my own armored.
