Just don't holster it loaded with your finger on the trigger 
You can always take your 1911 some other time when you get a holster for it. CDP is limited to 8+1 rounds. So you'll have to run downloaded... but it's what I do with my USP45.
Go. Be safe. Have fun!
It's a blast! I still remember my first time. Was great to do things that you just can't do at ordinary ranges.
