We don’t know when Zimmerman had his gun out. If Zimmerman had it out at the time it got physical, it would make sense for Martin to want to beat Zimmerman, because he would have thought Zimmerman was planning to shoot him.

Some of these “conjectures” seem to coming further and further from left field (or is it from Bizarro World?).
