I kind of liken this to when people disapproved of my converting one of my XD 45 Tacticals to 460 Rowland. Why? Because I could, why not, and it ticked off Glock fanboy friends of mine with their 10mm Glocks. And, by the way, the 460 Rowland has both more velocity AND energy than 10mm. Now if someone offered an upfit kit to take the P320 45 to 460 Rowland, I'd be all for that.
