Welcome to OCDO.
You would have better luck getting the technical details of your state's laws if you posted in the section for the state you live in. (There are at least two possibilities of which state you live in that immediately come to mind.)
"to carry my 9mm on my waist is it" - you are talking about your handgun in a holster that is attached to your belt, right? That's usually referred to as an OWB (Outside the Waist Band) type holster - for obvious reasons.
Check your state's section of OCDO to see if there are any meet&greet events happening. Meeting fellow OCers is always good, and for a newbie the chance to pump an experienced mind for knowledge is a great thing. If there is not a meet&greet happening in your area, start one! Pick a place & time, then post that you will be there. If one person shows up it was a success. If you plan another one it was a success. And if nobody shows up, plan another one anyhow - sometimes you need to let folks know it OK to be seen OCing in a group
stay safe.
