Looks like combs come in full and extra full. My gun is thick but not as thick as some shown here. It looks more like the A1S shown by Dean, ie it has the typical comb nose but a much thicker stock than standard.

Brian, you are right on when it comes to my gun as the DAC and DAH are both 1 1/2".

Trap guns always have a higher comb...are straighter to compensate for a rising target
