Only in brawls. Gotta get the "fists of steal " perk (i guess that′s the name of it).
Btw, if you enchant soul trap in the gauntlets, can yo trap a soul by punching, or is it impossible?
You can't enchant Soul Trap into gauntlets.
You can, however, enchant "Fortify Fist Damage" or something like that, which stacks with the heavy armor bonus and perk, which stacks with the Khajiit.
I mean it's pretty damn powerful. Out damages a Daedric Warhammer, and is about 4x faster. I made a very capable Khajiit brawler, but ended up quitting halfway through the Companions questline.
