I can't talk about the MC Operator, all be it, I have heard it's a fantastic platform. I own a TRP Operator, that I won at a match. It's a fantastic handgun in and of it's own... but, my GO TO (1911) gun, believe it or not.... is a Taurus PT-1911. I shoot single stack with it and it drives tacks. I have over 3k rounds through it, zero issues. It feeds empty cases, from McCormick mags... not picky at all. My TRP stopped on me during a stage once... I never shot it again in a match. Not saying Taurus trumps a Springer, not by a long shot. But, in my experience, my Springer is MUCH more finicky than my PT1911...
But, if I had to chose a full sized .45... I reach for my G21 all day long. I shoot ESP with it... and it has NEVER failed me. Ever. Period. :)
My TRP stays in the safe.
Just my humble .02 on the matter... YMMV.
