Looking for a quality OWB holster, preferably leather, for M1911 w/ Surefire X300U

So I have the option of carrying a personal weapon for court duty, and I'd like to start carrying my Springfield Operator M1911 with Surefire X300U-B.

I'd be wearing this in a suit, so what are some recommendations for something that rides close to the body, and is secure?
Thanks!
