Is there any reason why the Polymer80 PF940C frame wouldn't be legal in ESP/CCP? https://www.polymer80.com/pistol-frames/pf940c-80-compact-pistol-frame-kit/p80-pf940cv1 Anyone have any experience or know anyone who shoots one of these in sanctioned matches? I've read through the rule book several times and they aren't specifically banned. I've also searched around and can't find a definite "No". Any help would be appreciated.
