New to forums. Just picked up my PO7 Duty about two weeks ago. Left the decocker on. I use a Springfield XD (4", not compact) paddle holster by Blackhawk. For more concealment I use the Desantis IWB that I molded to the Duty for a better fit (and cut it down slightly). Desantis was maybe $27 and Blackhawk was $45 (but I think I overpaid at local shop, I'm new in town).
(Sorry, don't know how to post em, but the paddle holster is a beauty with carbon fiber finish)
