Came across a 2 piece CZ5 that appears to be original equipment. Thought I had a vast knowledge from the original CZ6 to the newest CZ3D but this is a first for me me. Any input appreciated and as I don't travel 2 piece suits me fine but if you have a two piece or know of one just let me know as we are always learning...I guesstimate somewhere along the line they experimented with a two piece shaft as even the original CZ6 was a 3 piece.
