I have a brawler who has Snake Style, Hamatula Strike & pre-reqs. Can he attack with his fists using Snake Style to do piercing damage and then get a free grapple check via Hamatula Strike?
Yes. hamatula strike isn't a style feat, you don't have to be in a particular style to use it. You would still take a -4 penalty to grapple checks to damage if you do that, or you can attack as normal with an unarmed strike
Thankyou, I'm going to use this to make the arguement to my DM that I can grapple with my elbows. :)
Unarmed Strike: "A brawler may attack with fists, elbows, knees, and feet."
