How is the M 39 doing in the market ? Mine is a great little pistol. I picked up the factory adjustable sight. I'm amazed at accuracy and how flat it shoots compared to pumpkin slingers like the 45 acp.
If you're plinking tin cans at 100 yards, the trajectory difference would be noticeable, but at a practical handgun range, I don't think it would amount to much.
I'm reminded of the .41 Magnum fanboy argument, how it's flatter shooting than the .44 Magnum, the fact of the matter being that it won't do anything the .44 Magnum can't do!
