Add To:

The Geissele Super 3 Gun (S3G) trigger is a semi-automatic-only derivative of the two-stage Super Select-Fire (SSF) combat trigger that Geissele Automatics produces for customers in the U.S. Special Operations Community. The S3G was developed to combine the SSF combat trigger’s match-grade semi-automatic performance with its smooth single-stage full-automatic feel to make a fast, smooth, and robust trigger ideal for 3 Gun competition shooting.

Note: The S3G trigger has a very short, light pull and reset. We do not recommend it for duty use, bench rest, accuracy work or shooting small groups. It is designed for close course competition use where rapid target engagement with quick follow up shots are required.

Is it a binary trigger ?
Jaydee on May 27, 2019
BEST ANSWER: No, it is simply a very light clean/crisp pull single stage trigger meant for competition shooting.

If you are looking for a binary trigger, I suggest looking at Fostech. Franklin armory also makes a binary trigger, which is a little cheaper but Fostech is better quality in my opinion.

Be sure to do your research and make sure binary triggers are legal in your state

Worth Every Penny! An unbelievably smooth trigger with no grit or creep. I’m running it with the installed 4-4.5 Pound Hammer spring and it is so quick and smooth. Best trigger I have ever pulled!

Great trigger for the intended purpose
I'll take some getting used to. The break is clean and crisp; reset crazy short. I used the 4lb spring option, and it works well for me. Follow-up shots are incredibly fast and dbl taps are a breeze. If you want to shed lead quickly with your AR platform, consider the S3G - I like mine a lot.

Very high quality
Very nice trigger. I assembled using the 4.5# spring.
I prefer single stage triggers and this is an excellent example of one. Installed in a Rock River lower. Fit was perfect.
There is not a lot of travel but, enough so that you shouldn't have an AD if you practice proper trigger control. There is the SLIGHTEST bit of creep (~1/16") if you're trying to use this as a precision trigger.
Where it shines is follow up shots.
I do not practice 'riding the reset' and could see where that could lead to bump firing it (noted in instructions).
With the short travel, quick and positive reset, + good trigger control it is quite easy to string shots together without much effort.
A premium product and carries a premium price tag. If you can get this on sale.. snatch it up.

You get it all
Simply one of the best.Have one in my Stag 3GL and im sold. Bought another for my SPR build and likely put one in my DMR Build as well. Its hard to part with the cashbut its the best improvement in accuracy.

A high quality upgrade.
Installed this trigger in my 6920 Colt and love it! These triggers are high priced that's my only gripe. Otherwise you won't be sorry about pulling the trigger on one of these triggers!
