I know someone who practically pockets his PF9, and it works well for him. He likes the reliability and accuracy for the low cost.
MOST impressive demo!
The smart carry with a pf9 is what I do for deep concealment and it is a very fast draw when you have your clothing tucked in correctly.
The only issue is that it can really get in the way of things when you walk and when you sit. You kinda have to move the smart carry around to find the right spot to prevent crowding.
Depending on my attire I occasionally have to use my Ruger LCP instead of the Kel-tec pf9
Supertuck or an ankle rig works for me.
Ill chime in for the SmartCarry. Love mine! I carry a 191 now but I carried a Taurus PT 24/7 Pro in .45 which is a double stack with an extra mag. No one ever noticed. From going to funerals to replacing engine and transmissions, I have mine on all the time.
