The CBST is great for great big guns but overkill for your application. It is also important that you realize that many holsters are not designed for 3:00. One that is, will work great for your application and is a moderately priced but high quality custom leather is a Nick Mathews #1. Nick specifically designs this for 3:00 and his quality is equal to $100+ holsters. He has a quick turnaround right now because he shut down for a while during a recent move.
My personal favorite, especially for a smaller pistol is Brommeland Gunleather's Max Con V. If you're into leather craftsmanship, this is the ultimate and you'll pay for at $120-$150. However, it is definitely a 4:00 IWB and typically a three month wait.
