You can't go wrong with any thing from Galco or Bianchi. I carry a Galco Fletch High Ride OWB and a Bianchi Professional 100 IWB. My only other word of advice is go leather.

Mernickle seems to have good products and I just ordered and received an ammo carrier from them. Seems very well made. They did say they are 6 to 8 weeks out on holster production however.
