You won't have any mechanical issues with either the Krieghoff or the Merkel. It's all a matter of feel. Handle them both and make a determination. The main mechanical difference between the two is the tang mounted cocking lever on the Krieghoff. Me, I'm a Merkel man for many reasons, but I like the feel of the Krieghoff better. I've shot the Krieghoff .500 in Vintage Cup events and shoot the rifle very well. If I got a Merkel, I'd have it altered slightly to fit me better. I can buy a Merkel, have it altered, and still have money left over that would've gone to the Krieghoff.
