guns I love
The legendary novalight- it had one inch punch, bashing and something else for perks, with a focussed nozzle for one of the mods. at close range, a shot to the face usually put things down. if not, a smack to the face finished it.
The AA-9 rigged up with a scope for range.
Any fast dagger. the v-attack on them takes things down pretty solidly. Especially if you have decent perks. Usually keep one quick-slotted for if the pistol I keep for close range goes out of ammo. It's faster to swap, I think, than to reload. I
the urban eagle is also a solid choice, for much the same reasons as the novalight up top- if it's got decent perks, (none of the procs, save those for things like the grendel.) and you can consistently get headshots, it does it's job well.
weapons I hate: anything with space adept. just saying.
