Can somebody tells me the differense in "feel" betwen Sig's trigger groups DA/SA, DAK (DAO) and SRT. A video on Youtube would be great !

I have uset SW5906TSW in IPSC-Prodution with a DA/SA trigger group an trigger weight 7,5/5,5, how does this trigger group compair to Sig ?

Is SRT konsidered as a god choise on a carry gun and for IDPA SSP divisjon shooting.

I don’t have videos any more, but I’ll try to give you the best I can.

DA/SA (TDA- traditional double action) is Sigs standard trigger. It is usually a double action 1st shot from a de-cocked gun with subsequent shots being single action. This is a NON-SRT trigger, but the SRT can be installed on this style trigger. It is about as basic as it gets with a usually pretty heavy (10lbs+) double action, followed by a long reset and lots of take up for a 5-6lbs, decently crisp single action.

SRT (Short Rest Trigger) is a device installed on TDA trigger systems that shortens the reset of the SA trigger by about 60%. It is drastically shorter. Though, it doesn’t address the issue of the long take up (movement the trigger moves before the sear trips the hammer) and doesn’t offer any pull weight advantages.

DAO (Double Action Only, not DAK) is pretty much a TDA without a single action. It has a long heavy pull that is just about the same as the TDA trigger aside from the hammer follows it back down. These guns are usually seen with a standard hammer, but no decocker lever.

DAK (don’t know what it stands for) is a double action only system with a MUCH better pull (not quite as good as Para Ordnance’s LDA, but nice nonetheless) than traditional DAO guns. The pull is I think in the 8lbs range, and it’s still long, but it’s been greatly smoothed out. So you still have a long Sig pull, but the weight is dropped a little big and it’s a lot smoother. If they could put a DAK style DA on the regular guns that would be really nice.

Grayguns- Bruce Gray, Scott Folk (Flork) and Torie (there’s probably more, but I don’t know you…sorry) run Grayguns Inc in Oregon. Bruce has been in the business for a good long while now and is pretty much the “go to guy” for custom Sig work. Personally having owned and own a few of Bruce’s subjects I can say that they live up to that name. I’ve had Bruce’s Competition Short Reset and it’s every bit as short as the factory SRT, but that’s where the similarities stop. Just talking triggers, I’ve never felt a better Sig trigger. The DA is literally a smooth and glass. There’s no stacking or roughness, just pull the 7-8lbs trigger and the gun goes off. The SA you have some options on. He can put a little roll in it or make it extremely crisp. Pull weights are subjective and individual, but for a RANGE ONLY GUN (must emphasize that) my P220ST was sitting right at 3lbs and felt like 2lbs. I haven’t felt a DAK or DAO gun of there’s, but considering what they can do with a regular trigger, I’m sure they’re just as stellar.

As for the second question I’ve carried a Sig P226 Elite in .40S&W with the SRT and shot a little IDPA (un-sanctioned) with it and it proved only to be better than the factory because of the shorter reset the splits came down a little.

I hope this offers a little insight for you…

A good write-up by Aaron above to which I can't and won't add much.

If your S&W is like every other 3rd gen S&W that I've shot, it's going to most similar to a DA/SA SIG with the SRT installed. S&W's have really short resets, and the standard SIG's DA/SA reset will feel a mile long to you. The DA weight however will be more than 7.5lbs, unless you get some great trigger work done on it.

Never seen a youtube video, but someone will probably make one someday.

That someone was me. I had video of a GGI 220ST, Sig Blackwater (stock) and P226 Elite all show trigger weights, resets and take ups. But they were lost in the great hard drive crash of 07'.

DAK-(for Double Action Kellerman, after the designer of the system). When firing the pistol the first trigger pull is only 6.5 lbf (compared to 12 lbf for the standard DAO). After the pistol fires and the trigger is released forward the trigger has an intermediate reset point that is approximately halfway to the trigger at rest position. The trigger pull from this intermediate reset point is 8.5 lbf. If the trigger is released all the way forward, this will engage the primary trigger reset and have a trigger pull of 6.5 lbf. To engage the intermediate reset the trigger must be held to the rear while the slide is cycled, either manually or by the recoil of a round being fired.

That sounds complex. Wonder why it's not just one pull...hmm.

The intermediate reset true design was to reduce the chances of short stroking the reset and if you have a bad primer strike at 6.5lbs, you're chances of second strike at 8.5 lbs going off increases greatly.

You can say that again!!!

Sig Sauer 250 DAO trigger is deskribed as "smoth" and light, how does it compare to the other sig triggergroups.

Smooth, light and looong.

That's why we use external back-up hard drives
