G34 with SRO and TLR1. Currently using a Werkz holster on a Boss hanger (I don't like this setup, want to find a better belt loop that is Bladetech or Safariland compatible that has rotation adjustment) , Ghost mag pouches and NexBelt. 5.11 vest for concealment.
I do not recommend a single point of attachment holster hanger for IDPA. They work fine for USPSA using a double belt system, but even a NexBelt is not rigid enough for a clean release of the gun from the holster using a single point hanger such as a Boss or a Henning. Better off using a two point loop straddling your belt loop. Single point hangers also run the risk of the subjective rulings on "suitable for everyday use".
