I would look at the bandito setup at
www.pistolpackaging.com.
After using a bianchi accumold belt holster and frequently feeling like my pants were about to go south (taurus raging bull), I purchased a bandito setup and am very happy with it. At first I thought it was somewhat expensive, but it is well worth it and they have very good customer service. The holster can be removed from the shoulder strap and used as a reg belt holster.
I purchased the bandito setup after reading positive reviews on a number of websites, including this one.
If you purchase a setup from them, follow their recommended sizing as I was just below a larger size and purchased the larger size. The size they recommended would have fit me just fine and left plenty of room for adjustment.
I would highly recommend a leather holster over a nylon holster, as leather holsters are much quieter.
