I took my Sigma apart yesterday to clean it. I got carried away and decided to implement some trigger updates. I did some light polishing, swapped one of the sear springs and put it back together. Noticeable difference as the trigger is much lighter than before-BUT-I have a problem wherein the the top sear pin (the one the trigger rod pushes on) keeps falling out after repeated dry-firing of the gun. I can pull it back down and see that the top pin is physically coming out of the holes in the sear bracket. I swapped back to the factory dual spring set up, and yet the problem continues. Anybody have any ideas as to why this might be happening? There is nothing to physically hold that pin in place. Perhaps when I opened it up, there was something there and it fell out and I did not see it fall?
Otherwise, I have studied it very carefully, and cannot see what would hold it in place. I could modify the trigger rod to include a tab (tig weld) but maybe there is something obvious I am missing. If someone has a picture of their gun with the slide removed, I would very much appreciate seeing it.
Also, I see that a lot of posts state that there has not been much success at modifying the triggers in the Sigmas and yet Midway sells different springs just for this purpose???? Should I just leave it as the factory intended-or is it really possible to modify the pull? If it matters-I have successfully modified the trigger in several other guns I own. Some with more success (lighter pull, less creep) than others, but still I have achieved a level of success with each & every one. Why not the Sigma?
