SIG DA/SA vs DAK

[skeetgunner]

The standard out of the box SIG DAK trigger pull is 7lbs; regardless of model. The DA trigger pull is 10lbs. Why the 3lbs discrepancy?

 

[RePete]

The trigger group is a modular unit compared to the standard.

Different mechanisms...the DAK was set at a 'substantial' pullweight to please
Police and military higher ups whose prime concern in choice of firearm is
keeping the number of accidental/negligent discharges to a minimum.
It's also less of a hassle for police and military trainers to coach converts from other trigger systems or new shooters to a single, consistent trigger pull.
Ask any experienced range shooter which system they prefer, and the majority will voice a preference for a either a dedicated single action trigger, or else a cocked double action trigger.

That would imply that a P220 and a P220 DAK are not parts interchangable, correct?

An excellent question...any Sig 'gurus' able to field this?

 

[redleg]

DAK guns were made on slightly modified frames. All new frames are so modified, but older ones cannot be DAK modified. Unfortunately I am not guru enough to let you know what the serial number ranges are.

People who have used them, say that the trigger reset takes some getting used to.

 

[foxbat]

DAK is double action only by any interpretation...
It's a long, heavy pull...If it was what I was mandated to carry everyday, I
would train with it until I felt comfortable with it...
Otherwise, give me a single action or a cocked double action trigger..anytime!

DAK and DA/Sa pistols (at least newer models) share the same frame. If you have a DA/SA you can send it to SIG to have a DAK upgrade for around 250$ including their refurb package. If you have an older Sig it can be sent back for the old school DAO.

Can the DA be sweetened up at all on the 220/226? Like having it done on a revolver?

 

[Colin]

Well the pull on my 226 is improving as it is fired, so I expect a gunsmith could improve it.

 

[skeetgunner]

All good replies, and I've learned a lot. But the thrust of my orginal question still remains, so I'll rephrase:

Since out of the box trigger pull of the Sig P220 DA/SA is 10lbs/4.5lbs and the P220 DAK is 7.5lbs, can the DA/SA be modifed to a 7.5/4.5 pull weight?

And I think the answer is no, yes and maybe:

no: the DAK uses a different mech. than the DA/SA.

yes: newer DA/SA frames can be moded to DAK (not quite what I want) so

maybe: it is possible to have a 7.5/4.5 DA/SA trigger unit?

 

[ffgats]

yes you can, replace your main spring-(wolff) reduce powwer,

 

[covert ops]

Polishing trigger parts and a wolf reduced power spring will help but thats a lot to shave off a trigger pull. When you go for reduced power springs you reduce reliability in that you may have 'light strikes' especially if you use harder primers. It would be nice to drop the DA pull and leave the SA the same but that isn't going to happen.
Any mods that you do will have an effect on both DA/SA and you probally dont want to drop the SA 2.5 pounds

When Langdon was still offering smith work, he had offered this:
LTT modifications included:
- Level Two Trigger Job with LTT Speed Bump Trigger
- Dawson Fiber Optic Front Sight, 0.090" red
- Tactical (extended) Magazine Button
- #18 Hammer Spring for SIG
- Black Hex Grip Screws

Before DA/SA = 11 lbs. DA, 6 lbs. SA
After DA/SA = 7.25 lbs. DA, 3.5 lbs. SA


Bruce Gray is another well known SIG smith and IPSC shooter, and he tunes 226's down to DA about 6.5-7lbs and SA about 3-3.5 lbs

So yes, people do exactly the work you were asking for.
