This is not the first time I've read of the fire on reset with the ACT and they had problems with the thickness of the coating interfering with safety function.
This a large-pin Colt by chance? Worth asking. Once it a while I see one with small pins in it. Works fine until you shoot it.
This problem isn't necessarily the trigger's fault-- "tolerance stackup" is real. Everything might be within tolerance but everything going exactly the wrong way.
I'm not a huge Geissele trigger guy because I'm not a huge aftermarket trigger guy. Of this type of trigger that I discourage the police from using on patrol rifles, I think the Geisseles are one of the best. From what I've see the quality and engineering brains are definitely there. Not to say it's impossible for there to be something wrong with it though.
Correct me if I'm wrong Ned, were the large pin Colts within a certain time frame? That was my impression, though I'm fairly ignorant on that topic.
FWIW, I have seen similar behavior from ALG trigger. Had to swap a regular run of the mill milspec trigger to solve the problem. Since these are milspec triggers, may be someone needs to tell us where to measure and inform others of the measurements.
The early ACTs used oversized pins, but ALG soon switched to standard ones. Amy sent me a new set of pins and even replaced an ACT that had noticeable creep. Double check the installation and lower; if those aren't right then contact ALG. I'm sure they'll make it right.
