Have shot the TRP Operator and the MIL-SPEC, the TRP will out shoot the mil-spec hands down. The TRP does NOT like lead bullets, stay with jacketed. Also the Operator in both models are recoil friendly due to their excessive weight due to utility rail machined into the frame. Holsters are another issue to consider, you're limited.
I personally own the TRP Pro in stainless,not the operator, it's the most accurate 1911 I've owned.( have had all Kimbers, baers, Colts.) My opinion only from past experiences of shooting for over
35 years
