New here - general question

My question is - how good/experienced do I need to be to get started?

I know matches say "new shooters welcome", but I'm sure there's an amount of experience you're supposed to have. I'm new to the idea of competition, not new to shooting. I am competent with a handgun, have about 15 hours of shoot-house shoot/dont-shoot scenarios (tactical security training, not competition related). I can shoot 10-inch groups at 10 yards under pressure, and have a 3x3 (draw, fire 3, reload fire 3, reload fire 3) at 10 ft in 7.2 sec. Hoping that gives you enough of a sense to tell me if I should keep practicing before I sign up or if I should send it (and what division/level/etc and all that stuff?)
