Sig DAK System
THE SIG DAK SYSTEM
My PD was issued conventional DA/SA Sig 226s & 228s in 9mm in 1988. In the fall of 2004 we transitioned to the DAK Sigs in .40 in the 226 and 229.
At that time Sig was offering a great trade-in deal. We got the DAK guns with night sights for about $125 plus the trade in of the old guns. (officers had the option to buy their old guns if they wanted and a few guys (including the recently retired) did so)
We weren't sure which trigger mode to get but some email correspondence with my mentor and advisor John Farnam convinced me that the DAK system was the way to go. (www.defense-training.com) (or directly at [email protected].)
The DAK trigger is unusual in that there are TWO sear set points. The closer reset point is about 8 lbs of pull, and the far sear set point is about 6.5 lbs of pull. It's hard to explain, but easier to understand once you have an example to shoot or at least dry fire a little. Apparently, one of the design parameters for SIG was to have a "second strike" capability in case of a misfire. I'm not sure if that's crucial or not, but it was something they considered when Herr Kellerman designed the new trigger system.
After some experimentation, we put factory "short" triggers in all the guns to reduce the length of pull between the backstrap and the face of the trigger, thus giving the user a little more leverage. I have big hands and long fingers and still I shot better with a short trigger. (I read someplace that all the DAK Sigs that DHS ordered had short triggers, but I don't know that for a fact)
When shooting, it works best FOR ME if I contact the face of the trigger with the pad of my finger. Some like contacting the face of the trigger with the crease of the first joint, like on a revolver. What option works best for you depends on the length of your fingers and your grip strength. When I shot the DAK with the crease of the first joint in contact with the trigger, I tended to pull shots high right.
I'd like the DAK better if the trigger stroke was shorter. The trigger stroke is light but L-O-N-G.
If you or your PD adopts the DAK Sig, get the Sig 239-DAK authorized as an option for shooters with smaller hands. The reach to the trigger with the DAK is long for every shot, and if you have females with small hands, their scores will go DOWN with the DAK, unless you get them a gun with a thinner grip.
I've had a number of my officers REALLY mad at me since we made the switch -- they were used to that short/light sear reset in SA mode and haven't practiced enough to get used to the DAK.
I shoot IPSC and IDPA matches at the local level once in a while, and I found that with the DAK Sig I had to downshift about half a gear to manage the long trigger stroke and still get accurate hits. (And I'm not that fast to begin with . . . being smooth & accurate is my game, rather than speed)
All in all, as an instructor I guess I'm SLIGHTLY more comfortable with my PD having self-decocking guns. Once in a while the mildly baffled/inexperienced shooter will reholster or move with the traditional DA/SA gun still cocked, and if they do that in a simple shooting exercise on the square range, they're much more likely to do it under stress. Having a self-decocking gun precludes this as a possibility.
