You just equip em, if I recall correctly. I didn’t try it myself, but it definitely is possible:

You still have to attack using LT (on controller) to get the offhand pistol to shoot.
You’re being downvoted, but it’s true. Will it further enable lazy/dumb people to continue being lazy/dumb? Absolutely. But summarizing notes, generating boilerplate emails or script blocks, etc. was never deep, rigorous thinking to begin with. People literally said the same thing about handheld calculators, word processors, etc. Will some methods/techniques become esoteric as more and more mundane tasks are automated away? Almost certainly. Is that inherently a bad thing? Not in the majority of cases, in my opinion.
And before anyone chimes in with students abusing this tech and thus not becoming properly educated: All this means, is that various methods for gauging whether a student has achieved the baseline in any given subject will need to be implemented, e.g. proctored hand-written exams, homework structured in such a way that AI cannot easily do it, etc.
