I've tried to do what he does with the 870s, and it is not that easy. First off, even the smoothest pump is very hard to cycle when you pin them under your armpits. Then you have to take into account how the ejecting shell would more than likely be blocked and jam up the action. Then when you try to swing them back up to the ready by twirling them by the trigger guard, the weight of the gun sets off the triggers. So he would only be capable of doing it if he flicked the safeties on, and you can see he didn't (at least, they probably cut it out for time constraints). So it is cool to watch but very tactically inefficient and not very easy to do in real life. But who cares? It's a movie.
When I saw The Rundown for the first time, I was like "Stop unloading the guns and tossing them away and just USE them!" but he's like "When I use guns, bad things happen to people." I rolled my eyes, believing this guy was going to be some pacifist brawler who someone would take on a million guys with his bare hands. I was relieved (actually, I was more like "HELL YEAH!") when he picks up the 870s and the rock music begins.
