Was at the range today and got to chatting about holsters . We each had 5” m&p 9’s mine a pc model. All of us have various kydex holsters . Well the discussion came around to the new 5.7 and the 22 mag and the question of would they need a new holster or be compatible with your existing holster, just curious even though we’re all going to get one or the other . So whose got the and knows?
