I'm asking this as a thought exercise, because I understand the human factors involved in DA/SA operation. But with the trend towards the P320 and other pre-cocked strikers, aren't folks effectively carrying condition zero pistols? Have passive safeties and increased gun handling evolved to the point where this is safe?
In another thread I posed the question as to whether decocking a DA/SA pistol is strictly necessary. In the case of the Walther P99AS, the SA mode is identical to the PPQ. If a shooter were to not decock a P99AS, the safety level would be the same.
I understand the history of the DA/SA design, and the fact that basically every organization carried their pistols in Condition 3 until Cooper came up with the idea of carrying cocked and locked. My experience in the military reinforced the wisdom of this, when a guy shot himself in the ass with a half-cocked 1911. The perception was that revolvers were safe to carry ready to fire due to the double action and long heavy trigger. Thus, Walther adapts this to semi-auto pistols in the PPK to allow for a ready round in DA mode. (I don't for sure, but I'd bet that most organizations still carried condition 3, due to the least common denominator) It's my contention that the gun using public and organizations have adapted to the Glock, with finger-off-the-trigger discipline (not a thing in the '70s and before), so now Condition Zero is acceptable.
So, how does that apply to a Sig P226 or Beretta 92FS? Presumably, the pistols are drop safe in SA mode. If the hammers were to slip off the sears the firing pin safeties would prevent discharge. The standard triggers are 4.5-5 lbs with plenty of travel.
