Quoted from Dobe: "For those of you who like DAK, why did you chose DAK. You are giving up a single action pull, or at least a single action pull eventually."
OK, so I cannot shoot SA with a DAK weapon. I do not consider that a problem. While it might be convenient to be able to switch to SA in some isolated circumstances, I prefer the consistent pulls of DAK, and I am not less accurate when shooting DA, when shooting realistically, offhand, or from an imperfect improvised rest. With a TDA, which of my shots is most likely to be outside the rest of the group? The second one, which is the first SA shot. Training minimizes this, but the tendency is still there.
I long ago learned to shoot SA-only, with 1911 pistols, DA, with various sixguns, and TDA, with a P220 first, about 1990. In 2002, I learned the Glock trigger. I shot best, overall, with DA sixguns. In 2004, I picked up my first DAK P229, and it was like coming home. Unable to carry a DA sixgun as a duty handgun since 1997, in 2004, I had my favorite trigger stroke again, combined with twice as many rounds available than a sixgun. What's not to like?
Yes, when I can stretch out, and get onto a really good, solid rest, I can do good work with SA fire, if I take my time. That is unlikely to happen in police work or private citizen defense.
Some say SA is faster for follow-up shots. Perhaps, but with alloy-framed pistols chambered for .40 S&W, I find that by the time my pistol has recovered from recoil, the trigger has reset to the full forward DAK position. Others' results may vary.
I am not trying to convert anyone to DAK, and totally respect someone who prefers TDA. I recently obtained not just one, but two special-run P229s with stainless-steel frames, and TDA actions. Life is good.
