Security six hammer problem

[chopperdoc]

I have a 1976 4” Security Six. A few days ago I disassembled it to replace the serrated trigger with a smooth trigger. I got the trigger group reinstalled without any problems and when I pull the hammer the transfer bar moves as it should and the cylinder pawl engages the cylinder as it should. The cylinder rotates as it should.

My problem is installing the hammer. I’ve tried it at least ten times. Every time I install the hammer and install the hammer pin I cock it back and it will fall when I pull the trigger but when I pull the trigger a second time it is locked up. (This is without the mainspring installed) When I depress the cylinder release and move the cylinder out then lock it back it in again it “resets” the trigger and I am able to once again drop the hammer only once before it locks up again.

The gun worked fine before I messed with it. Any help is greatly appreciated.

Thanks

The key phrase here seems to be "the gun worked fine before I messed with it". Let me give what the problem could be some thought.

Triggers in revolvers are not necessarily swappable without fitting. I don't have a SS but I do have RHs which are apparently a similar system. I think the mainspring is important to the trigger reset in these revolvers, have you given it a try with the mainspring in? You should be able to reset the trigger manually by pushing it forward after pulling it to release the hammer.

Put the original trigger back and see if the gun functions.

If so ..... maybe there's your answer.

So I reinstalled the original trigger. Hammer went in easy as pie.

Strange cause when I hold the two triggers side by side they sure looked the same.

No worries, I ply paid ten bucks for the smooth one. My 2 1/2 inch blue security six has the smooth trigger and I just liked the way it felt better than the serrated trigger.

Thanks for the help

Glad it all worked out.
I feel so fortunate to have a couple of competent and reasonable local gunsmiths in the area!

I would love to see close up, side by side pictures of the two triggers, left side, right side, and rear. But if you could only take pics of the one that gave you problems, that would help also. I've swapped out a lot of Six series triggers and hammers and have never had a problem like you described, there's got to be something different and it could be very small and easily overlooked.
