They are two different guns entirely... specifically noting the "Cocking System" of the Kreighoff.

Do you like it? Can you get used to it?

Most DR guys don't like the Kreighoff, primarily b/c it's something that they're not used to and feel that they will "Forget to do" in a heated moment when muscle memory takes over. Is it "safer" - I believe your best "safety" is between your ears.

If you don't like it and get ready to sell it, I think you could probably move the Merkel faster - given the comment above, but Hey - it only takes one buyer.

It's your money and your gun... get the one you like best.

And if at all possible - buy used. The Euro will kill you on the purchase of a new one and a used one is likely to have been shot very little (why else would he have sold it) and should be in good shape.

You should have little problem finding a used merkel.
