Lost pin causing SA inconsistencies?

[65Whelen]

I swear there's a black hole under my work bench. Re-assembling my 629 I dropped the pin that goes in the trigger rebound spring and poof it's gone. Looked high and low no luck. My question is what does that pin do? I ordered some wolf spring and was trying different pound rebound springs that they offer. Didn't like them. When I was reinstalling the factory spring is when the pin went missing. I don't see what the purpose of this pin. It fits inside and just floats inside the recoil spring and that fits inside the trigger return spring housing.

Now the really good news. I put the 629 back together minus the pin, SA is a nice 3.25 pound DA is 12 pounds. But SA when I pull the trigger ever so lightly the hammer drops but trigger moves forward into its nutrual position. Not always, maybe 1 out of 5 times and I'm pretty sure it would not fire when it happens. It doesn't happen when I'm firm on the trigger.

Any idea as to what's going on to the single action inconsistencies? Is it related to the missing pin or is it something else?

I'm surprised a 629 has one. I think it is a trigger stop of sorts. I have two n frames that I accidently did not put them back in and they function fine. My first N frame had one and I thought it was a stray piece of metal.

As noted, it is a trigger stop, to reduce overtravel of the trigger during single action fire.

It's a trigger over-travel stop pin. Not necessary for reliable function, just eliminates most of the trigger over travel when firing single action.

If the factory spring was returning the trigger before you removed the pin it should be ok. I would take the rebound slide back out and clean everything. Put a very light coating of grease on it and put it back together and try it again

They come and go! Some N frame guns do not have them, and frankly I have not found them to be much use. I put them back into guns that have them, but do not worry one bit if the gun does not have one.
