I just wanted to pass along some product info.
As I get older, I get a little less enthusiastic about shooting hot shotgun loads with a pistol grip on a pump shotgun.
There is a company called Speedfeed that makes a very rounded and contoured pistol grip. It is downright comfortable in my hands, even on cold days. It used to hurt shooting #4 and #6 shot duplex loads from the Remington 870, but no longer.
Cheaper Than Dirt sells them.....
