I've been quite pleased with Comp-Tac's International holster model. Their mag pouches also work well.
The IDPA world champion has been a long-time Safariland 5189 holster user.
Any of the kydex outside the waistband holsters that are intended for IDPA or IPSC shooting from big name companies, or good copies from small producers, should serve you well. IPSC rules allow high tech race holsters that aren't permitted in IDPA or USPSA's Production Division. If you're not within 2% of the national champions' scores in a match, there's no chance a change of holster might win the match for you.
