@vcdgrips, FWIW:
A GEN5 MOS gets one a flexible platform, with the potential plate failure point. If the plates are mounted correctly (@SoCalDep), there have been only one or two sight issues I'm recalling off the top of my head. Not mounting the plate/sight combo correctly has led to mounting failures. So, the direct mill cut removes that obviously. We just had a nearby county S.O.go to direct mill G47s with ACROs a few months ago-so far so good, but not a lot of time on the platforms. You get in view some benefits from the GEN5s; measurably improved accuracy as one example.
I'm invested in the Glock platform, obviously, from my posts. My latest daydream wish is a direct milled 19 for and ACRO and standard trigger. I don't think that's being made yet...
