It does not fit Bladetech holsters. You can heat it all you want but the trigger guard will not lock into the holster. It will fit and lock into the Comp-tac holster. Cranking down the tension screws on the Bladetech did nothing to secure it any better. It would not be suitable for competition due to the fact it would fall ,out easily.
