I pesonally don't carry a 9 much, when I do it's usually a smaller pocket gun, Ruger LC9s Pro or Taurus G2C. I bought a lot of Underwood 124 gr Gold Dot's a few years back, good ammo but likely still better out there now. I do have a FN 509 I could carry IWB, I just don't. I usually carry a XD40 SC, XDS40, or a G2C in 40. Underwood 155 Gr XTP's.
