Non-Critical Dimension?
I think that this is a Non-Critical Dimension as the critical dimensions are those where the trigger must mate with the frame with such precision as to allow the sear/disconnector to function while permitting reasonable repeatability in the trigger function. (Huh?) that means that the trigger travel after the sear/firing pin breakpoint is non-consequential in a combat pistol, and the overall width was probably finished by hand to asthetically please the eye of the grinder/polisher after the critical dimensions were within specifications. Probably done on a hand jig based on the trigger pivot point and then polished.
that's my two engineering cents of speculation
