The Superiority of the DAK System: A Case for Smoothness and Precision In the world of trigger systems, smoothness reigns supreme when it comes to improving accuracy, control, and overall shooting performance. While single-action and striker-fired systems have often been praised for their light and crisp trigger pulls, they are fundamentally limited by the presence of a wall that disrupts the fluidity of the pull. In contrast, double-action systems, particularly double-action only (DAO) configurations like SIG Sauer’s Double Action Kellerman (DAK) trigger, offer a far superior experience when it comes to the smoothness and consistency of each shot. Designed with both simplicity and reliability in mind, the DAK system not only provides a superior trigger experience but is also the ideal choice for defensive shooting scenarios where control, predictability, and accuracy matter most. What Makes the DAK System Special? The DAK system, created by SIG Sauer, is a double-action only (DAO) trigger system that was initially designed to simplify the mechanics of the firearm while maintaining a consistent and smooth trigger pull. It was developed primarily for law enforcement and defensive use, where simplicity, reliability, and ease of training were paramount. The DAK trigger system eliminates the complexities and inconsistencies of double-action/single-action (DA/SA) triggers by providing a consistent, smooth, and linear trigger pull for every shot, removing the need to manually cock the hammer between shots or switch between different trigger modes. The Proper and Improper Use of the DAK’s Resets What truly sets the DAK system apart is its dual reset feature. Unlike traditional DAO systems that have a single reset, the DAK offers two distinct trigger reset points: 1. The First Reset: This occurs earlier in the trigger’s return and results in a heavier but still smooth trigger pull. While this reset was included for emergency purposes-particularly if the shooter short-strokes the trigger in a high-stress situation-it is not intended for regular use. Unfortunately, many police departments and training facilities misinterpreted this feature and trained officers to use the first reset for faster follow-up shots. This was a misstep, as the first reset, while still smooth, is significantly heavier and more difficult to manage than the second reset. 2. The Second Reset: This occurs further out along the trigger’s return and results in a lighter and even smoother pull. This is where the DAK system truly shines. When used correctly-releasing the trigger all the way out to the second reset-the shooter experiences an exceptionally smooth, consistent pull, making follow-up shots both faster and more accurate than if they were relying on the first reset. SIG Sauer themselves clarified that the proper use of the DAK system involves releasing the trigger fully to the second reset between shots, ensuring that the shooter benefits from the lightest, smoothest pull possible. This method optimizes the DAK’s strengths, allowing the shooter to maintain accuracy without fighting against unnecessary trigger weight or friction. Momentum and Smoothness in the DAK System One of the most significant advantages of the DAK system lies in its ability to maintain momentum throughout the trigger pull. In single-action and striker-fired systems, shooters are often interrupted by the presence of a wall, an increase in resistance just before the trigger breaks. This wall can prevent the shooter from building momentum, as they must stop and apply additional pressure to overcome it. In contrast, the DAK system’s smooth, linear pull allows shooters to apply pressure gradually, with no sudden increases in resistance. This means that as the shooter pulls the trigger, they build up momentum naturally, making the trigger break feel effortless and predictable. The absence of a wall in the DAK system provides a crucial advantage in defensive shooting scenarios. When you are under stress, you may not have the fine motor control to handle the abrupt transition in pressure that comes with a single-action or striker-fired trigger. The DAK’s continuous pull, on the other hand, allows you to maintain control throughout the process, leading to more consistent, accurate shots. This is especially important in situations where speed and precision are essential. The DAK System vs. Single Action and Striker-Fired Triggers One of the primary limitations of single-action and striker-fired systems is their inherent wall, which disrupts the smoothness of the pull. While these systems are often praised for their light trigger pulls, the wall creates a distinct stopping point that the shooter must overcome, making the pull feel mechanical and less fluid. This not only affects the shooter’s accuracy but also prevents them from using momentum to assist in the trigger press. In contrast, the DAK system has no such wall, allowing for a continuous, linear pull. Because of this, shooters can apply pressure gradually, using the smoothness of the system to generate momentum and overcome the trigger weight without experiencing the abrupt resistance typical of single-action or striker-fired designs. While these systems might offer lighter trigger pulls, they lack the fluidity that the DAK system provides, making the DAK a superior choice for those who prioritize smoothness, predictability, and control. Why Smoothness Matters More Than Trigger Weight Many shooters mistakenly believe that lighter trigger pulls are inherently better, but this overlooks the importance of smoothness in the overall shooting experience. A heavy but smooth trigger, like the DAK, can feel significantly lighter and more manageable than a light but gritty trigger, particularly in high-stress situations where control is paramount. In the case of the DAK system, the smoothness of the trigger pull allows shooters to build momentum throughout the press, making it feel lighter and easier to control than its actual weight. In defensive shooting scenarios, where accuracy, speed, and consistency are critical, smoothness often outweighs trigger weight in importance. The DAK’s smooth, linear pull allows for faster follow-up shots and more consistent performance under pressure, making it a superior choice for defensive use. Additionally, the lack of stacking and the early break in the DAK trigger ensures that shooters don’t experience the sudden jarring sensation that can occur in double-action/single-action systems, where the trigger pull becomes progressively heavier toward the end. Conclusion: The DAK System’s Superiority In conclusion, the DAK system represents the pinnacle of smooth, consistent trigger design. Unlike single-action or striker-fired systems, which are hampered by the presence of a wall, the DAK system offers a continuous, linear pull that allows shooters to build momentum and maintain control throughout the trigger press. The dual reset feature, when used correctly, provides a smooth, predictable trigger experience that enhances accuracy and follow-up speed. The DAK system stands out as a superior trigger for defensive use, where smoothness, consistency, and control are paramount. By eliminating the complexities of DA/SA systems and offering a simple yet refined trigger pull, the DAK delivers a shooting experience that is unmatched in its predictability, precision, and ease of use. For shooters who prioritize smoothness over mere trigger weight, the DAK is the ultimate choice, proving that a well-designed DAO system can outperform single-action or striker-fired triggers in real-world scenarios.
6 years later the exact deal can be found from GT. I didn't pay for hand select but got a much more pristine condition just by luck. No night sight on mine. They work great and are super accurate for 340. Dak is a nice change from SA/DA. I agree with the sharp trigger - replaced with a Grayguns adjustable flat trigger for 60. More comfort, less after travel.
While the price may be lower, it's not exclusively because of the .40 or the DAK, the SRT/DAK function is amazing and it is definitely one of the best triggers SIG has ever put out which is saying a lot. A lot of folks just don't want to train with it, which is silly. If you carry a revolver or a 1911 you require fairly extensive training, and "Glock-leg" is a term for a reason. This gun manages to cross-section several features on several great firearms, again, like the LEM :). Two trigger systems that need more understanding.
I just got one more or less like new $400. P226 Stainless. The trigger pull took me a few rounds to get use to. I am old and don't see that well so I added a laser site for the longer targets and got good results. Up close it is very easy for me to hold a 4 to 5 inch pattern. Super nice gun with great grip. You can get a 9 MM barrel for under $200 and it takes less than two or three min. to change over. There is also a 357 barrel. Great gun for cheap.
Highly underrated because of the DAK trigger, but the design of the pistol is one of the best, if not The best, out there, and as iconic as a Browning Hi-Power, CZ75, or Beretta 92. The .40S&W, as well as the DAK, will almost always be associated with law enforcement, but I believe that in time, these will go up in value, and in the meantime, you can enjoy shooting the heck out of it. With that said, I'd be disappointed with the condition of yours, given you paid a hand pick fee, but it's always luck of the draw. The LE mags are usually non-reflective, be they parkerized or bead-blasted, in the case of stainless. For me, there are no better ergonomics than the P220 series Sigs. Next time, you should include some shooting footage. Cheers
just picked one (like new) for $450, traded an old duty USP .40 that I loved but....I Got three others so....Anyway, this is my third SIG, P220, SP2022 (best DA trigger of all I've tested, okay SA, P220 is superb of course). the SIG P226 /w E2 grips, DAK, is damn near the perfect carry gun...only gun I like carrying more out of all the Glocks and Berettas and Springfield XDms and Smith and WEsson M&P (minus the shield, that is the bee's knees)....anyway, got a DA/SA SRT kit and 9mm barrel, the e2 grips and it's basically back up to the easily sellable $850 range. Though I plan on keeping it forever unless I use it as partial trade for a les baer or Ed Brown or a good SIG 1911, or a SIG P226 Equinox, X-Five, Pardini, HK P7M8 or M13...lolll
Dude, I just pick up p226R dak in 40cal for 329.00 from AIMSURPLUS in mint condition, Put some Hogue extreme g10 piranha grips in blk/gry and got .357 sig barrel. loving it! it's my new EDC, carry with .357 sig Hornady 135 grain critical duty. Range time is 40 cal 180grian win white box or rem green box, Not one FTF OR FTE with either Caliber. one pistol two different calibers. TOTAL COME UP big time. Don't even fuck with the G19 anymore, since I got this sexy bitch.....
I agree on all points. Bobbed hammer definitely a plus for CCW, DA for added holstering safety, and .357Sig is a great round (and the .40 has its advantages too).
Own a few HKs, Glocks, Beretta, this and the HK P2000 LEM are my favorites for carry (next to my Smith and Wesson M&P Shield my hubby got me for xmas, performance center too, the green and red sights made it very x-mas-y! hehe) I'm good with revolvers and DA/DAO style triggers so this is perfect. Smooth and as crisp as the best revolver out there, I actually haven't felt a revolver DA trigger that is as smooth as this. The LEM is a different beast altogether but mastering the DAK would help with the LEM, and some vice-versa...like Saxaphone/Clarinet or something.
iam confused about something. the man says this is a dao gun. i thought that with a dao gun each trigger pull is the same, but with this gun you can have two differant trigger pulls one short and one long was i wrong thinking that with a dao gun each trigger pull is the same
my opinion you’re not wrong thinking that. In every other case with a double action trigger the pull weight would be the same every time. That’s why this is such an odd ball trigger. It is still a double action trigger because every time you pull the trigger you are also pulling the hammer back. As far as the mechanics of how it works I wouldn’t even be able to explain. Because I have no clue how it’s able to do this. But it does and it’s a very unique shooting experience.
@@BrowncoatNerd HELLO from canada and thanx for the response bak. ok its the excepection in this case i understand now . enjoyed your vid . i have a p320 were every pull is the same...striker fired. it was advertised to me via the local gun store that it was dao but some people debate that . i like this dak and will see if i can rent it at the range
You are full of crap. The German ones had terrible triggers and were harder to shoot accurately. I was in on the U.S. ground floor presentation to L.E.
