Please don't knock the doubles. Even in the PD they were issued to the old time detectives that used them while serving warrants, etc.. Many of these men were not very familiar with the Remington and Ithaca pumps that we used and it was for safety reasons that the doubles were issued. These shotguns were cut down and extremely easy to move about when in close quarters. Believe me a double can be a fine HD gun and I wouldn't feel under gunned using it either.
You have to realize that most people have no training with pumps, which does require a certain amount of training to be proficient in it's use. Also, it's important to know that many incidents in the home occur while the homeowners are woken up from their sleep and are not clear headed. The pump being handled while half asleep can be very dangerous for others, as well as the intruder. At least the double with little effort can be checked to see if it's loaded. This is just my opinion.
