Ok folks, a pal of mine has a 410k and a 400 classic for hunting and HFT. He wants to have a 400k and 410 classic.

To me the easiest way is to swap the cylinder and barrel. Obviously power will need to be altered when the barrel length changes, which isn't a problem.

Having never worked on these rifles before does the cylinder just screw off when empty? I'd rather not take Andrea's out of the stock to find out!

Thanks in advance.
