Trigger question

[chamber143]

I have a drop in trigger, a very expensive one at that and i love the trigger. Only peeve is that the trigger pin likes to walk a good ways to where one side is out pretty far and the other is below flush. I have a 1000 round 2 day course this weekend and i am worried to death it going to walk all the way out. I have never had a trigger pin as much as move before this trigger. It is said that these triggers will move on the pin until it finds a point of no friction, maybe so but i dont like it. Is anyone else’s trigger pins do this. Yes i have contacted manufacturer and they were very helpful and said the pin was doing its job. I dont want a pissing match, i just finally broke down and bought what is considered one of the best triggers on the market and have been left under whelmed with the pin movement, not the trigger. Lower is a Noveske gen 1 registered sbr lower and has been flawless and i had a pnt trigger that never moved if that helps.

A pin designed to take a little stroll? How special. Slight rotation during firing is not uncommon What brand and model? Some triggers are suggested to use anti-rotation/walk pins. If time permits, I'd suggest purchasing a set. Perhaps clean the particular pin end well along with that area of the rcvr and put a dab of silicone there.

I am dumbfounded as well but i really dont want to put them on blast. They specifically warn against using anti rotation pins with their triggers if that helps

Sorry, just reread your post. You do have a drop in. In that case I have noting to offer. I'm not a fan of drop-in triggers for a couple of reasons, and that is one of them. Hope you get it fixed in time.

Maybe drop in isn’t correct terms. Its not a one piece. It has the trigger, hammer and disconnector and pins. It goes together just like milspec

The hammer pin doesn’t move at all and yes the legs sit on one side of the trigger pin.

The hammer spring legs should straddle the trigger, one on the pin on each side of the trigger.

The legs need to seat into the groove(s) on either end of the trigger pin. The trigger pin should have a groove on one end or both ends. 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.

I think Giessele pins are slightly oversized. Might want to give them a try.
