Gun tests gives Kel-Tec PF-9 am F rating.
Gun test magazine August 2010 (pg. 24) Gives the PF-9 an "F" rating. "This pistol had the most felt recoil and was the least accurate -- We suspect from the heavy trigger."
This was among 11 other 9mm pistols (tested in 2007) beginning with the Springfield P192029LP which retailed at $1253.00.
I have to totally disagree with the review. While I would not give the PF-9 an "A" rating I think it deserves a "B-" or "C+" all things considered. It is a light weight 9mm pistol and as such it would have significant recoil. But for a pistol that can be had for well under $300.00 (Typically $259.00) I consider a decent buy.
