I have a pair of Gen 5 23 MOS pistols inbound, to see how they work out as red dot field pistols. Plan to run one with a 23 lower, and the other with a G45 lower ( with a .40 ejector). P2 Acro as soon as I can get my hands in one, although a P1 for now with a TD Acro plate. Need to sort out heights for BUIS. Will get a JM AIWB with and without a light. Looks like US Duty makes a RDS retention holster for the G5 Glock 22 MOS. Will be running Underwood Lehigh penetrator ammo and need to decide on a tough JHP load. Look forward to assessing reliability first, then shootability.
