I run with
Ump 45 silenced
Spas 12 Extended mags or grip
flash bang
Semtex
Marathon pro
Stopping power pro
Ninja pro
killstreaks 7, 11, 25
or killstreaks 5 7 9 (pred, harrier, pavelow)
people never expect people to be rushing all the time, and i can spawn trap one person and kill him over and over till i get my 7 killstreak. gotta love the fail spawn system on demolition... so easy to get nukes
