    Geissele FTW

    I shot the SD3G on a timer for the first time yesterday. Shooting multiples I averaged 0.13-0.14s time between shots! Most of that comes from practice, but part of that speed comes from the trigger.

    People don't rave about Geissele's products for no reason - their triggers are very well thought, very well made, and very reliable. If you are doubling on the SD3G, you're probably bumping it a bit. I have found that this is really easy to do with any light(ish) trigger, especially from a bipod.

    I can't wait to see what Geissele comes out with next.

Although he doesn't realize it the short reset of the trigger that most find so desirable is too short and his finger is actually pulling the trigger back through the reset.

    It seems like very experienced shooters have this problem more because they have developed trigger control to put just enough force into the trigger to drop the hammer.

    It is important to understand that triggers on bolt guns and triggers on semi auto guns are fundamentally different. With a bolt gun the shooters hand comes off the gun to work the bolt, the trigger does not have a finger on it during this time. A semi auto reloads itself in a flash while the shooter still has his finger on the trigger. This is a whole different dynamic.

    Here is what I can do to help. Send your trigger back in and we will increase reset and provide a additional trigger spring 1 lb heavier. This will make the trigger less prone to bump firing. There is no need to suffer with a trigger that is not up to your expectations, we will get you fixed up straightaway.

    Thanks for the reply Bill. As mentioned my intent for this trigger is a 5.56 rifle geared for 3 gun, however I wished to try it in the .308 precision rifle due to the claimed "feel" of the single stage like pull. I will very much say that it does feel more single stage like as opposed to a two stage feel, but I also understand the possible shortcomings of the trigger especially in a heavier recoiling gas rifle combined with a certain trigger pull type or what I consider a correct pull type on a precision rifle.

    On that first range day after quickly inspecting the install and some dry manipulations and closely watching the engagements of the 2 stages, I was dead set (still am) that it was a bump-fire situation and purposely tried to mimic that. In reality a slow or controlled trigger press just past the second stage sear release when the hammer is tripped is was what I felt to be the biggest issue as the first stage is virtually kept out of play or more correct that the engagement is so short that it virtually goes unnoticed. So considering the counter recoil on a gas gun with a reciprocating bolt, especially on a heavier caliber weapon, this easily leads to the bump fire condition when using what I consider to be a correct precision rifle trigger pull. So I do agree with your assessment on the experienced precision rifle shooter and that type of trigger manipulation used there as I couldn't get the rifle to bump fire with a sloppier pull or a "press and flip" type of pull and I understand when this type of pull has its advantages which is not ideal for precision fire. Also a hard, hold to the rear of the trigger didn't allow for the bump fire during the rifles counter recoil phase so I know the trigger isn't slipping off the sear prematurely before I did a trigger reset. I know you understand all of this, but for those reading it may help them to understand what might be happening if they are having similar issues.

    I very much understand various methods for running a trigger on both a handgun and a rife and I use various methods weapon, trigger and use dependent so I understand what niche this trigger was designed for. I completely acknowledge that I am attempting to use the trigger in a manner that you really didn't intend it to be used. I will however say that I didn't fully expect to run into this issue, or more correctly expect it to be as pronounced as it was. Without adjusting the triggers reset I am going to simply try a different spring combo just to suit my own curiosity but I understand the short reset will still exist. When your SD-C trigger arrives with the final parts for my 5.56 build the triggers will get swapped. If I continue to have issues, I will let you know if I need an adjustment made on the trigger. I very much appreciate your product and your desire to satisfy your customers as your products and customer service has never been a concern of mine. I will also say that I would also love to see a quality single stage in the 4-5lb range at a good price and look forward to seeing what you come out with.

    I have several Geissele triggers. My first was the SSA. Unlike most of the posters here, I am having opposite effects with the 3 gun triggers. I have the S3G and the SD-3G. As of right now, I do not know what 3G configuration I like the best, but I have to say that it is my favorite trigger. I am more of a combat/get a ton of rounds on target quickly type shooter. I only shoot out to about 320 yards max. I shoot MOC instead of MOA. I have experience with very light single stage triggers, two stage triggers and the S3G triggers. I have no issues with doubling whatsoever. I have only had issues with the lighter single stage triggers in the form of wanting to shoot let's say a string of 4 rounds and maybe getting off 5 instead. As far as I am concerned, if that extra round is still on target, I feel it is a non issue.
    If anyone wants to dump their S3G triggers, don't hesitate to shoot me a PM!

    Surf,

    First of all thanks for a very informative Youtube channel!

    Secondly, I encountered a similar problem with an S3G.
    I had used plain GI spec colt trigger on my carbine, and found the 3.5lb S3G a bit light, which when combined with the short take-up resulted in an occasional "extra" shot.
    I found out that Bill was preparing a 5lb spring for the ARFCOM billet lower project, and installed it; it is the same gold colored spring the previous poster mentioned. The pull weight went to a flat 5lbs, and I have used the trigger in a Pat Rogers EAG class without a single incident.
    Get one and you will be pleased.
    Regards,

    Jorge

    Just a heads up for those interested. Again this is a .308 Noveske based rifle, not a 5.56 and I think this makes a definite difference as in a heavier recoil and reciprocating mass on the counter recoil phase.
    Edit - Sorry but I think it is important to also mention that even on a gas gun precision rifle with a pistol style grip, I DO NOT wrap my thumb around the pistol grip. I ride the ambi selector on the same side as I work the trigger as I feel it helps to promote very fine accuracy. I also feel that this can contribute but not the only reason for the issue I was having.


    I went back to the range to do some testing. Again with what I consider a better trigger manipulation on a precision rifle I had some doubles on the stock S3G trigger and springs. With a strong pull and more precise or forceful hold to the rear with the trigger manipulation I had no issues but the trigger pull was less than what I would consider ideal.

    I next did a spring swap for a USGI set up. Trigger pull increased and I didn't experience any doubles. The trigger was good, but I would opt to perhaps try a 4-5lb spring set up and try to leave the reset length alone. If I altered the reset length and springs then I would believe that I would just end up with one of the other Geissele triggers, so I will leave it at that. Maybe Bill can comment more on that. I actually want to leave it alone to run in the 5.56 3 gun rifle and last night I built up my 5.56 3 gun rifle and put the S3G in that rifle and put in a SDC in the .308.

    Here are the offenders.

    Thanks again Bill for commenting on the thread and offering your support!

    Just an update. Putting out some good rounds via the S3G trigger and not a single issue so far running the S3G in the 5.56 rifle.

    A little speed test with the S3G vs a Colt USGI. I actually find my VTAC 1-5 drills to be far better but I truly believe that it is due to the actual weight and feel of the new rifle build as opposed to the S3G trigger and this is from looking at splits. I will say that the trigger is a part of the new rifle's feel, but not the overwhelming factor where I am dipping into the 2 second barrier on this drill.

    I did find a bit more consistency with the S3G but in all fairness we are talking in the .01-.02 hundredths of seconds range. I will also note that by the time I got to the VTAC 1-5 drill with the Colt USGI, my trigger finger was pretty spent after about 500 rounds or so. All of those rounds were pure speed drills so the trigger finger was pretty gassed by that point. I will also note that the constant switching between trigger types created an issue than if I were to only run one type and I ran the USGI trigger on the VTAC after the S3G which I think was a factor for some inconsistency issues just due to the different pulls.

    I plan on doing a more in depth accuracy testing with a red dot optic and see at what point, if any, that I can actually attest to having better accuracy due to the trigger itself.

    I would call or e-mail them. I was in the same boat after reading a bit of info here. I contacted them and received one 4lb and one 5lb spring a few days later. I prefer the 4lb spring for my uses.
