Looks like a beauty!
Question, where are you finding the bbl.'s for the 2240?
One thing that bugs me about this pistol is that it is a left hand bolt.The bolt is on the right side, which is correct for a RH rifle. But if you shoot the pistol RH, then the bolt should be on the left side, where you can work it with your left hand.
How about 2240 with a Repeater BNM breech.
