Depends on what I'm wearing. Light clothing eg. Shorts I carry my LCP. If I am dressed light or normal I carry my LC9, and if wearing a jacket or heavy clothing I carry my SR40c.
I choose to regulate weapon to what I'm wearing because I don't support Open carry as it causes to much worry and unrest by individuals who see it and I don't see the point of making someone feel unsafe. I know if I see a open gun my first thought isn't a good one. So I choose to conceal because I'm the only person who needs to know that I'm armed.
