Question about choosing a stealth gear holster

I just got my first handgun last week, a Glock 19, Im not sure what holster to get I feel the stealth gear is a good choice for my first one, people seam to be very happy with them. now I'm not sure what one to get the ventcore or the revolution. Im very active so idk if one would be better then the other. I would like to carry at 4 o'clock, also can the mini be warn at 4 o'clock ? just curious incase i might want to aiwb carry sometimes. I'm 5' 10 160 lbs is that helps any. thnaks
