This is a fine argument to have, both are great guns. I lean heavily toward the Model 12, especially in 16 gauge. My 16 is an original field grade, 28" barrel, modified choke, weighs 6 1/2#. I can't imagine a better chukar gun. I also like the heavier ribbed 12 gauge Model 12s; they point beautifully for me.

Maybe the greatest reason to prefer the Model 12 is that it looks so nice next to a Model 42...
