[What If...?] How did Killmonger...

...wield the infinity stones? In the What If finale, Killmonger takes the stones from the dead infinity ultron and manages to wield them with no visible effort. It took all the the Guardians to hold a single one, Iron man died when he used them all, and even Thanos was visibly struggling when he got the final one in infinity war. 

But Killmonger manages to somehow steal Ultrons armor and wield all but one. How? 

Was it the armor? Could the Avengers have made a vibraniam gauntlet in Endgame in order to snap without hurting themselves?

It was the armor. The Avengers could have probably made a better protection device if they had had more time. Ultron specifically created the body he had to hold the Infinity Stones and he was also much more intelligent and cognizant of the stones powers than the Avengers.
