OK, hold on...
Be advised that there is the Micro Compact and Marine Corps Operator....which one are you talking about?
One is 5" the other is 3"
I'm guessing that you're talking about the 3" as that's what you said you wanted...
Generally speaking, the MC Operator is the 5" gun.
I know it's confusing, but if you talk to a shop / holster maker and order a "MC" Operator and accessories for the same, and not the Micro-Compact, you're going to be really, really, surprised at what you get.
