Mind that this is all in SR4 mechanics as this is where they are in my own writings.
There was a time when the character in question would have been the one that technomancer, who would have been the one to reveal the pair of Stick-N-Shock loaded holdouts in hidden arms slides up both sleeves, showing the willingness to follow one of Murphy's laws: "When in doubt, empty your magazine." If there's more to deal with after that, the Ruger Super Warhawk with Ex-Explosive loads at his hip.
As of now it would be a speed test to see if he could get his similarly equipped pair of modified Ares Redlines out to shoot before his girlfriend decides to either slap said ork with a stunbolt or torch said ork with a flamethrower spell. Besides the change in artillery the only other change is that he's no longer a technomancer. Still wouldn't change his base reaction to said surly ork. If there's more after that he's got an APDS loaded Predator IV at the hip and she's as good a conjurer as she is a spellslinger.
Sadly I won't answer for them in SR5 terminology, as it would spoil my plans for them, though in the very least it could still be the same speed test to see if he can shoot before she incinerates said ork in this scenario.
