Are you using this as a back up to your UMP? I used an UMP for almost 3 years (and will hopefully be rolling with one again here) and carried a TM 4.3 Hi Cappa (will also be doing this again here when I'm ready) as a back up to that. A shotgun is awesome, I'm planning on getting one, but the fact is that in real world usage using it as a back up to a main is not going to be the right choice. Just my 2 cents....
