Red Hill Tactical gets my vote, been using one for IPSC/USPSA for the 3 years and have no intention of changing back to DAA or Blade tech.
If you use the code redmagnum it will get you 10% off.
Agreed Red Hill makes some good stuff! Lots of colours, and the quality is great. Also look at getting a BOSS hanger to mount the holster to the belt, if you get the BOSS hanger from Ben Stoeger Pro Shop, they have good holsters too!
