I'm awaiting on the shipment of a full size 45 w/5.31" threaded barrel to arrive from Bud's. Anyone have this gun? I wanted the pc version similar to the 10mm, but it's nowhere to be found. I foresee more m&p's to be in my possession soon! What I need is the 4.6" 10mm (w/manual safety or not it doesn't matter) as then to have all 3 lengths. What I can't find is a custom maker that offers more than just factory replacements for the 10 and 45? wanting to get extended length w/ports.
