I just received via the great brown truck of joy a 2007 vintage 1858 Starr DA revolver. Nice in that it works smooth right out of the box. Neat design and after going over the parts schematic I've got it pretty well figured out as to the mechanics with one exception. There is a spring attached by a screw to the back of the primary trigger. Part# 19B and called a trigger safety spring. It looks like it can be adjusted up or down. I have an idea what it might be for but figured I would see if anyone who has experience with this revolver can tell me for sure.

Not enough coffee yet to take mine apart to look. I think moving it well change the trigger return pressure, but I really don't remember.

I think what you're looking at is the gizmo that switches the gun between "single action" and "double action." In one position it hits the secondary trigger, or "sear" when pulled causing the hammer to fall, in the other position it is out of the way, and the trigger must be released and you must pull that "secondary trigger" manually.
If your description is right ... and I'm awake enough .... ;-)

That was what I suspected. It looks as if when it is in the forward position it allows the primary trigger to contact the secondary trigger and fire double action and when it is down the tit on the spring allows the primary trigger to cock the weapon but not touch the secondary and fire it and you would have to use the secondary trigger single action to fire it. Ingenous! Wonder why they didn't mention it in the instruction. Italians, go figure. Thanks for the response.

This is from a site on the Starr originals.
Thanks for the responses guys.
I finally got it figured out. The mechanics of this are complicated yet simple at the same time. If that makes any sense. Actually the cocking trigger works just like a double action trigger and in that mode only moves the secondary trigger out of the way and continues the travel of the hammer until the cocking arm of the primary trigger clears the hammer pivot and the hammer drops. In single action you only pull the the cocking trigger untill the secondary trigger sear engages then let the cocking trigger forward and press the secondary trigger for a light single action release. That little spring on the trigger when fully up as delivered does nothing. Move it down and the tit on the spring engages the frame of the gun just before the double action releases giving you a short but heavy squeeze to release the hammer allowing you to use the sights double action or signaling that the revolver is cocked and you can release the cocking trigger and press the secondary trigger for a singal action release. I think I will just leave it in the all the way up position.
Cleaning should be a breeze as there is no way fouling can find it's way into the innards with this design. Although takedown and reassembly is pretty straight forward once you understand it.
MCB: I don't know how closely Pietta's design follows the original as on the Pietta the spring can not contact the secondary trigger in either position or maybe the reporter you sited was confused as to the purpose as I was. Still it's kind of a neat feature I just don't think I will use it as I don't need the rear sight for double action and it's easier to thumb cock it for single action.
