That would for sure fit in at least 2 holsters I have. Unless you're really scared about someone going for a grab (a billion to one odds that would happen in the coffee shop) and you want to wait for your retention holster, I've got ya covered. Up to you obviously, just do whatever you want. It's not a terrible idea to skip it this time if you aren't comfortable with the idea, nothing wrong with taking things slowly and carefully in regards to firearms. Plus it's not like security will be an issue.
A strudy leather belt of any kind will work great usually. I use a tool belt most days so I can carry my gun. 6 bucks, fits inside my belt loops just perfectly, and damn sturdy!
