Good luck with that search.
I have been a very happy PF-9 carrier for about 2 years now (CCW 5 Years) and have had no luck in finding nice gun leather designed for this great little 9mm gun.
Even though this gun has become a record breaking, prized and much sought after firearm by LEOs and Civilians, it seems the major players in the leather holster industry have not figued it out yet.
Until leather(designed for the Kel-Tec PF-9) is available try Desantis Nemisis Pocket Holster or perhaps an Uncle Mikes product Also I think Fobus has something in the works.
I have discovered that almost any nylon holster product designed for gun size instead of gun manufacture will work in a pinch.
To be safe regarding fit, it is best to choose a nylon holster with a retention system so your gun will stay put.
When Gun Specific LEATHER Holsters become available for our little gun you will find me in the front of the check-out line. STAY 360 DEGREES SAFE!!!
