To some a lock model is junk. To some anything but a pinned, and recessed, model is out of the question. I even had a clown, on another site, say a 3" 66-4 was worthless compared to a 3" 66-2 ONLY, ONLY, ONLY because the -4 has a rounded rear site rather than a squared.
I learned long ago not to argue with the mental midgets. It only gives them the attention they so desperately want/need.
