I just bought a P-10S OR and while I wait to pick it up (thanks Illinois) I was looking at all the fun upgrades I can get (Apex Tactical extended slide release, Hyve mag extensions and HBI theta trigger, extended mag release and reduced striker spring set), but that got me wondering what kind of parts compatibility there is with the P-10S and the P-10C. Any info would be so appreciated. Can't wait to pick up the new addition.
