Regarding the standard vs. QA versions of the P99, I favor the standard (traditional double action). It seems to me that the standard P99 competes with the HK USP, Sig, CZ, Beretta, etc. I feel safer with that longer, heavier first shot trigger pull. I figure I would only shoot double action if I had to draw and fire very quickly (probably at very close range). I don't think the long, heavy fist-shot trigger pull would be a huge factor at close range. About 99.9% of the time, I will have (and take) time to cock the pistol before firing - giving me a better trigger pull than a QA P99.
I think the QA version of the P99 competes with the Glock, Styer, and other pistols with short, light, double-action-only triggers. I recognize that many people like them and feel perfectly safe using them. I woudn't argue (much) with them. But knowing that my pistol is ready to fire at all times with just a short, relatively light trigger pull makes me a little nervous. I like the extra margin of safety provided by traditional double action. This was probably the biggest selling point, for me, of the P99 (actually, mine is an SW99, but same thing, right
). If I wanted something like the QA trigger, I'd just go with a Glock (less money and very well-proven design). I like having a streamlined, polymer framed, light, high capacity pistol that is traditional DA.
Regarding the Ruger pistols, I'm sure they are solid and reliable guns. But, to me, they don't look or feel as nice and refined as the Walther, HK, and other "higher end" pistols. Sort of like comparing a Chevy truck to a Mercedes. If you are looking for a less costly option, I'd check out the CZ pistols (75B or the lighter and more compact PCR model). These seem just as well designed and made as the "high end" pistols, but cost about the same as the Ruger. They are a little heavier than the plastic guns, however.
