So it sounds like this Fluff-n-buff" is a must-do procedure for a PF-9 or does it just depend? I have a new one that I haven't shot yet and am wondering if I should do that before I put any JHP through it (or just shoot it and see if it chokes and then do it if needed).I have a PF9, it has been flawless in operation with over 1000rds thru it. However, I did do the "fluff-n-buff" procedure that is posted on the Kel-tec forum before I fired it the first time.
