I carry my PPQ M2 IWB. Not a Navy model so no threaded barrel. It is by far the best pistol I own and have faith and confidence in its performance. Terrificly accurate, great pull, great ergo, hundreds of rounds through it without a single failure.
Point of reference: Beretta M9A1, G17, M&P 9mm and (apples to oranges) a Shield 9mm & XDS 9mm.
