Shotguns have a very specific purpose. In order to do well with a shotgun, you have to dictate every gunfight. If you're consistently losing to someone with a shotgun, it's because they're dictating the gunfight.
It is easy to dictate the fight with the shotgun because people keep running back for revenge. :-)
When I use one I will patrol a building or small area of the map so people keep coming back for more, but I am always on the move so they rarely run into me at the same spot.

Sorry that you need a crutch like the executioner to do well. The executioner kills faster than the shotguns in MW2 and has as much range and damage as the MP40.
Don't use the executioner. If you're tired of getting shot across the map, find a way around that. Sorry that you can't stop geting killed. --- "The normal make a living. The deranged make history." - Christopher Titus "A conservative is a liberal that has never been mugged." - Julie, The Maxx
