Tiny update:
Bought a TMC replica of the Safariland (579? GLS retention) holster with a mid ride paddle.
Cheap enough to not give a fuck about it but also lets me try the mid ride configuration, and if it works for me I'll buy the real deal (apparently it fits the AAP01 too, if it's true then it's a win-win).
Also bought some speed plates to give mags some protection in case I drop them when reloading.
Installed the ML rubber and I-Key but haven't had the chance to try it out yet because of the lockdown.
