SIG SAUER Short Reset Trigger (SRT) ?


October 12, 2010, 06:54 PM

I havn't been able to find much detailed information about the SRT option.

I am looking into getting a SIG P220 .45 Auto, and I would like to know what the SRT is all about.

1) What is the mechanical function of the SRT?

2) What are the up's and down's of the SRT?

3) Why do people get the SRT? Compared to DAK.

4) Why not to get the SRT?

Thanks in advance!

This is a description of it:

Short Reset Trigger package – This service retrofits your standard DA/SA trigger parts with a SRT system from our popular Elite, SAS Gen II, E2 and Tactical models. The SA mode trigger reset travel is reduced by 60% allowing for faster follow-up shots and rapid fire use. (Excludes SAO/DAK, P250, Mosquito, SigPro, P230/P232 models) $99.95

I have not personally used SRT, but I can find no down side, as the standard reset is quite long. (I've owned SIGs in the past.) Since you indicate you are buying a new one anyway, perhaps they will have a model with SRT already in it.

DAK sux.

there's no downside to the SRT.

I am not too familiar with terminology and handgun operation in general.

So, after you fire the first round, which is Double action, the following (Single action) shots are easier to squeeze off.

Can someone go more in depth into this? Because I can see this will affect many things...

First of all, does 60% less travel equate to less Trigger Weight?

So will the DA still be 10 lbs and SA would be only 1.76 lbs?

4.4 x 0.6 = 2.64
4.4 - 2.64 = 1.76

Second, in a tactical situation, what does this mean?

Thanks for the feedback!

I am also considering a GLOCK 22 GEN 4, are there any benefits in the GLOCK I am not seeing? It has up to 17 round clip of .40 cal, anything else?

1) What is the mechanical function of the SRT?

The Short Reset Trigger (SRT) shortens the reset of the trigger in SA

2) What are the up's and down's of the SRT?

up: If you have the training, the shorter reset of the SRT would allow you to shorten the time between accurate shots, because your trigger would have to move less to reset the trigger

down: Factory equipped SRT guns have a tendency to have both heavier and grittier trigger pulls, due to their increased engagement to insure safety

3) Why do people get the SRT? Compared to DAK.

The SRT was designed to compete for a LE contract with the S&W Gen 3 pistol. The S&W is renown for it's short reset in SA. Many folks equate short reset with faster accurate shooting.

The Double Action-Kellerman (DAK) is a modification to the Sig's DAO trigger sysytem. It offers a lighter and smoother DA trigger stroke (like a tuned revolver) with the option of a shorter (less than full release), but heavier, reset.

4) Why not to get the SRT?

Most people will never fully utilize the shorter reset, because they don't know how to correctly manage their trigger to it's potential. For those who do, there are other inherently safer modifications available.

If you have guns that have shorter resets and you fine that the longer reset of the regular 220 trigger causes you to short stroke the trigger (not releasing the trigger enough to reset), the SRT would offer a more consistent reset travel

nimbus, you need to rent some Sigs and try the various modes before you decide. Glock is the same trigger pull for each round, whch many people prefer. Some choose the DAK for this reason. Do your homework before putting down the cash.

The reduced travel has no effect on the DA and has no effect of the pull weight of the trigger at all

The 60% less travel refers to RESET, which refers to the point at which the mechanical trigger/hammer linkage re-engages, ready to fire the next shot by pulling the trigger.

It has nothing to do with the weight of the trigger pull.

The DA pull will be around 10#, the single action pull will be about 4# or 5#

Wonderful! I understand it now... thank you all so sooo much!!!

As the next generation P220, the Elite builds on the exceptional reputation of out-of-the-box accuracy with the addition of SIG’s new Short Reset Trigger or SRT. The SRT provides you the same great safety and smooth action of the SIG DA/SA with a comfortable short reset for faster trigger return and surgical control during high speed shooting.

Let me break this down for you as "newbie" as I can, as I don't know your firearms knowledge, training, or expertise levels. So please bear with me.

Obviously you know what SRT stands for Short Reset Trigger. SIG developed the SRT system to shorten the reset of handguns they make increasing accuracy, follow up shot times, and consistency.

So how does it work, it simply shortens the rest of the trigger, if you are curious you can do the following.

To see what your current pistols reset is as long as its not a 1911 pistol thats of high quality do the following:

1. Clear the gun, make sure there is no round in the camber, or a magazine in the gun.
2. Operate your slide to allow the gun to dry fire.
3. Pull the trigger and HOLD the trigger to the rear.
4. While holding the trigger to the rear, recock the gun.
5. after the gun as been recocked slowly release the trigger until you hear a click and the trigger "thrust" forward.

When the firearm clicks and the trigger "thrusts" forward that is the point of trigger reset on your firearm, the point of reset is wear the trigger can be immediately pulled again.

So based on where your reset is can effect many things, like groupings and how fast and accurately you can make a follow up shot(s). The farther your trigger has to go forward the more "play" you will have in hand position, point of impact, and overall operation.

With an SRT trigger the reset is what i can consider about 60% shorter than a standard firearm. If you own a high quality 1911 the reset is very close to or the same as your 1911, as 1911's usually come standard with a shorter reset trigger. And while most SIG platforms are based around a 1911 style frame/grip it mimics the use of a 1911.

To answer a few of your other questions: there is no down side to an SRT system, the less reset, and the faster you adapt to the trigger the faster you will have more consistent groups and follow up shots. The DAK trigger is a double action only pistol that is used by a few groups of the Government, while other groups use Sigs with SRT systems, its all based on what that agency whats there employees to carry.

A DAK trigger is no comparison to a SRT setup.

The only reason to stay away from a SRT is if you don't want to relearn shooting with this style, meaning you grew up on revolvers, mostly own and shoot revolvers.

I 100% recommend an SRT trigger system. But sometimes you have to experience it to understand. Do know you can add the SRT trigger to any DA/SA trigger system SIG for $80 in parts do it yourself or I think SIG charges 95-105$ to do the work including parts, but there turn around time is 3-4 weeks right now.

Good luck and happy shooting.
