That is what keeps the trigger pin from moving side to side. Get a super bright light and you should be able see the leg(s) of the hammer pin, and at least one should be in a groove on the trigger pin.

    Were both pins walking?

    Which pin was walking?

    Here is a Geissele trigger pin. One leg of the hammer spring must be in the groove indicated with the arrow. The other leg of the hammer spring must be on the pin on the other side, even if there is no groove. You don't use the center groove for the trigger. The center groove is what the hammer uses to center on the pin, but it sounds like you are GTG with the hammer.

    Ok here’s the deal. It’s a geiselle ssa. Awesome trigger. The trigger pin walks toward the side that the groove is on no matter what orientation it is. I even tried switching the trigger pin and hammer pin to see if that mattered but I doesn’t. The hammer pin does stick out a little but stopped and hasn’t moved anymore. The trigger pin is the issue. It hasn’t walked all the way out yet but it will get to where the groove on the end can’t go any further without coming out. As much as I love the feel of the trigger, this is on my fighting rifle and I don’t like the thought of it coming out. I’m anal about shit like this. I will run it through my class tomorrow and Sunday and if it’s gtg through 1000-1200 rounds than I’ll just love with it. Geiselle did say that they have a slightly oversized pin that has notched on both sides if I need that. I didn’t think the receiver holes were large because I have a BCM PNT and the pins didn’t move one bit. As much as that trigger is infinity better than the milspec trigger, the SSA is night and day better than both. So it would suck to go back to the PNT.

    A pic would help diagnose the issue. Maybe the hammer spring is installed backwards (commonly done) so it’s not exerting enough force on the pin. I’m not sure if you’ve fired your rifle with the new trigger yet, but if the spring is installed backwards it could lead to light primer strikes as well.

    It’s installed correctly. Yes I have already fired about 200 through it and it stays but my it gets so far out one side that I’m worried it will come all the way out. Like I stated I’m going to run it hard tomorrow and Sunday and see what happens. I always bring two spare rifles to my classes as backups but never needed them. Hopefully the trend continues.

    Now that we know the trigger, check the J-spring. If you googled, you see you're not alone with this issue with that particular anamoly.

    J spring? Its the spring that keeps the hammer pin centered. Its like a detent that fits in the groove in the middle of the hammer pin. Earlier, I think you said it held the pin in tightly.

    I would take up Geissele's offer to send you a slightly larger pin with a groove on each side, if I were you.

    It doesn't look like the pin is going to fall out, maybe you could show us the other side of the receiver?

    Also, you could install it in a different receiver to see if that's the problem.

    EDIT: You said that what ever side the trigger pin groove is on, is the direction the pin moves? Do both pins always move in the same direction when this happens? Did Geissele offer any possible explanations for what is happening.

    I would get that double grooved oversized pin from them and try it.

    If this photo is showing as far out as the pins go, then I don't see a problem. As long as the hammer spring is properly tensioned and one leg is sitting in the groove of the trigger pin, the trigger pin will stop as soon as the leg of the hammer spring meets the inside of your receiver wall. This could just be tolerances between the length of the pins, location of grooves and your receiver dimensions.

    I can wiggle the pins on my SSA slightly with light finger pressure, but they don’t walk out. Like the post above me I wouldn’t worry if the photo you shared is the extent of the walking. Mine hasn’t come out in over 4k rounds

    This photo was just showing the hammer because I know that many were saying maybe I had it on backwards. It will move about twice this far out. I just constantly push it back in during breaks of fire

    This is somewhat my thoughts too. The problem i see is that the legs are naturally bent inwards due to the strength of the spring so the pin will move the distance the legs will. On my other triggers when the hammer is not installed the legs are parallel with each other and the Geissele they are angles toward each other. So with other triggers the legs dont want to move one way or another but the geiselle wants to move back to the center allowing the pin to move that same distance if that makes any sense. In my head it doesn’t sound like its coming out right but i hope you guys understand.
