SRH TRIGGER WEIGHT

[wilecoyote]

.44 SRH: I feel the trigger weight, both in single (4lbs) and double action (7lbs), as definitely excessive. Kuhnausen has not published anything about the SRH afaik, so I ask if there is a source, a link, or some specific instructions here, to lighten above all the single and, just in case, also the double action_
thanks to all_

A 7lb trigger pull for a DA revolver is in competition shooting territory, I'd be extremely surprised if you could even find a professional to guarantee a better result.

SRH mechanism is the same type as GP-100, if you can find guidance for improving that trigger (it's available online, not sure about in a manual), that guidance would apply.

Wolfe makes a spring kit for the SRH. Changing the trigger return spring can help but be careful going too light on the mainspring or you will get light primer strikes

...too light striking is a problem I encountered working on S&W 19, that's why I ask first, here, before bothering even just the SRH single action

Gemini Customs claims they can tune a SRH to 2.5 lb SA and 9 lb DA. The first with some polishing and perhaps work on the sear by a professional could get you to 2.5 lbs. 7 lb DA seems very light. My GP100 which should have a lighter DA than a SRH (due to reduced mass of the parts) is 7.4 pounds measured a mechanical recording gauge (Chatillon) and down in the 6's using a Lyman electronic. The SRH has a better leverage inside than the GP medium frame but increased mass. The GP I have has the Wolff 8 pound trigger return spring and 9 pound mainspring in it and has been tuned by a professional gunsmith. Some sourcees for ideas are:

There are others. I would look at MCarbo which offers spring kits as they have a video on polishing et al of Ruger revolvers.
To get a low pull weight one must do judicious polishing, use tubing on the trigger plunger, get the correct shims for the hammer, hammer dog and perhaps the trigger, minimize endshake, minimize head space and maximize firing pin protrusion. The above are by no means exhaustive.

Kuhnhausen's Shop Manual on Ruger DA revolvers? IMHO, merely installing lighter springs does not equate to a trigger job. If your Super Redhawk is like most Ruger revolvers that I've had apart, it could greatly benefit from having the sear edge made suare and polished. After that, worry about springs. The one Redhawk that I owned had a 7-lb SA trigger pull as issued. Correcting the sear surface dropped that down to 5-lbs, which I found acceptable. Granted, a different lockwork than the Super Redhawk, bit I see no reason that the results wouldn't be comparable.

"A 7lb trigger pull for a DA revolver is in competition shooting territory, I'd be extremely surprised if you could even find a professional to guarantee a better result."

I agree with this. A 7 lb DA pull is quite light. If it's a smooth pull,, then I'd be happy with it. If not smooth,, then a careful polishing to smooth it up would be all I'd consider.
