I was thinking more of a Bobbed Grip frame like Hunt's.
I carry a full size 1911 pretty well. Commander even better, but in a rare moment when it digs in, it is usually the grip frame.

I am old school in believing that the Browning design works better with barrels 4" and longer. But that is just me. I have a couple of friends that carry and shoot the Defenders. They like them. Have not heard any complaints from them.

Gun Shows are almost as comical as boat ramps in the Spring.
