I recently bought a Krieghoff Classic Big Five in 375 NE FL.
Just got it back from the gunsmith who installed a detachable Zeiss HT 1-4, a decent recoil pad and
changed the pitch and lighten up the trigger a little bit.
Its not too heavy but I'm pretty sure its the big frame....

It weights 4486 g w/o scope and 5072 with.

Merry Christmas!
