I love statistics and survey and data crunching, however to cover every thing well it is beyond tedious and would send many of us to the loony bin :blink:! There are alot of variables when it comes to testing certain firearms and how you compare them to others... There summary in the most recent addition does not state why they failed the pistol and I disagree with them sometimes and here was one, I went out a bought a PF9. I have since sold it but not b/c I had any issues (I just wanted a J frame which was more versatile for me to carry in different positions) in fact a friend of mine has it and it is running fine for him too!
Here is the quote from that issue November 2007: "What we couldn’t tolerate was the trigger function. The trigger was the longest and heaviest of those tested, but we could have gotten used to it, if it were not for what we consider to be a design flaw. We believe in properly resetting the trigger after each shot to increase accuracy. After we fire a pistol we hold the trigger to the rear of the trigger guard and then release it forward until a click is heard, and then we apply steady pressure for the next shot. If you try that with this pistol, you will only hear a click instead of a bang.
According to the Kel-Tec manual on page 12 under the subhead "Malfunctioning," a misfire is most likely the result of faulty ammunition. Then, the manual continues, "Another potential cause is that the trigger was not allowed to fully reset after firing. The hammer is then dropped from the hammer block, which will not fire the cartridge.""
So they were staging the trigger for accuracy when they got their malfunctions... whether or not this was remedied by KT after 2007 their test pistol serial #R1541. I do not know but evidentally not many people listen/feel that first click when releasing the trigger, but I do not shoot the Sig DAK and am definitely not a huge authority on these things but I release my trigger all the way on all my pistols, I did not see why this was a problem for them and even though they allowed others at the range to shoot the KT they warned them of the trigger... is that posioning the sample, research and data is quite difficult to control... it is also possible they recv'd a lemon, it does after all happen, even to the "higher end companies".
I don't think they are intentionally biased, testing, recording and reporting make you the target because it is now in print, they are not my only source but they are one I use, if you only learn from one person you only know what they know and who they learned from... right? They often re-test some guns later, as the market changes so maybe they will or they won't, you could write or email them and see...
I think it is clear the PF 9 has a good reputation for what it is and it goes to show everyone of us has our preferences and should thoroughly test our equipment!
