Just curious folks...Is the 220 in 38 super the same gun as 220 in 45? In particular the slide. is there a difference in the front hole that the barrel rides on? I was wondering this since I want to buy the 38 super barrel for it and rechamber it for 9x23 winmag. Will this 38 barrel's Outside Diameter be the same as the 45 barrel? I don't have one to check but really getting the itch to do this conversion.
