So far I've only seen the two shot modifier (two shots per trigger pull), on tech handguns. Namely the Kenshin and the Quasar handguns. I just found a Kenshin with almost 900 DPS and I'm level 34, that's crazy, the normal DPS of that gun, without that modifier, is less than half that. These two shot guns are quietly some of the best, if not the best in the game, and I can't find any info as to which weapons have a chance to get this particular modifier. Another weird thing about this is that no matter how many times I craft either of those two guns, I can never get that modifier to roll. It seems to me like it's only available in a random drop and only available on very specific weapons. Does anybody have any more info on this?
