most of the time the problems with PF-9's are operator error. Most dont want to hear that...but its the fact.
Its a tiny little gun that packs a wallup to the hand/wrist. When i first got mine i occasionally had FTE's (stove pipes) wife had em much more frequently. What it comes down to is "limp wristing" the gun.
Get a grip on it, fire it often and allow the gun to break you in. As Cane talks about the 1911 500 breakin...the pf-9 requires the same...only its not just "breaking in" it own mechanical parts...its breaking in the shooter as well.
I am well over the 500 rd count in my pf-9 and i dont hesitate to EDC mine. (i much prefer the 1911..but its way to big for many of my carry situations where total and complete concealment are necessary)
