On the Wiley SP the front sight and insert are level and fire POI/POA with my carry load which is Hornady 140 357 FTX Critical Duty. On the 3" the front sight is a Trijicon night sight and to make POI?POI square up I hold the middle of the tritium vial level with the top of the trough of the rear sight. My practice load for both duplicates the Speer GDHP short barrel load. Hope this answers your question.
