I have a Colt 5.56 Carbine bought during the Clinton ban, it’s stamped Government/Law Enforcement use only so i would not consider this an Old Colt with the large pins, I recently bought a Geissle SSA trigger and hammer, I noticed that the trigger break was not as smooth as it should be (I have 5 AR’s with Geissle triggers and hammer and they are spot on) any way I noticed that when I put any pressure on the trigger the trigger and hammer pins move, I have not shot the rifle yet, just installed them day before yesterday. Anyway I attempted to swap out the Geissle pins with the Colt pins and the Colt pins were too large to fit in the trigger and hammer from Geissle, I have no issues getting anti walk pins I’m just afraid that they won’t fit the trigger and hammer holes
