The Don Hume IWB for my 1911 officer's size fits mine like a glove. A firm grip and a locked wrist is all it takes to shoot the PF9 comfortably. I don't care for any of the add on grips or mag extensions that make the gun bulkier or cling to clothing. A bigger grip should have a bigger gun attached to it, IMO. My range sessions seldom exceed a couple of mags with this pistol. Just enough to be comfortable with reliability, and maintain proficiency. I do not use it for high volume plinking. I have plenty of guns for range duty. If you keep it clean and properly lubed, it will serve you for a lifetime as an excellent little carry gun. Enjoy yours!
