Help Please--Ruger tang safety trigger.

[doorgunner]

Amazing to me that I posted a request for help on the Ruger Forum for instructions on how to adjust the trigger of my 770 series tang safety Ruger M77 and have had zero responses.

I conducted a search.  Tons of people laud the fact that the tang safety Ruger M77's have adjustable triggers, unlike the MKII's, but yet nobody knows how to adjust them.  Other posters have asked the same question, and there is either no reply, or they send the worn out link to the varmint hunters site that provides instructions on reducing the pull weight on a M77 MK II trigger.

The external allen screw that regulates the trigger spring compression does absolutely nothing.  I can tighten it, or back off of it, and it still breaks at a hair over 5.5 pounds.   OK, well if it's such a great asset over the Mk II, then how do I adjust it?

I've been a Remington man my whole life, and this is my first M77 tang safety.  I'm desperate here guys!

The Ruger trigger is adjustable although you may have to replace the spring..  Earlier 77's were fairly easy to adjust but evidently a heavier spring was substituted to make trigger return pressure higher on later rifles..  On the attached link to the parts blow up the adjustment screws are D-22 (sear engagement), D-43 (pull weight), and D-44 (over travel).  Unless you know exactly what your doing adjusting the sear engagement (D-22) can be very dangerous.  There is also an over travel set screw (D04501) to keep that adjustment from moving.  I strongly suggest a dab of epoxy to stop movement of any of these screws once they are where you wish them..

Thanks Gunnut!  I had pretty much decided that the big issue was going to be in the trigger compression spring, as there appears to be no discerable creep or overtravel.  I might do some additional toying with changing the spring, and see how that pans out.  Thanks for the link, and for the response.

Always remember the spring can be lighter as long as it provides enough pressure to return the trigger, BUT is has to be the same length.  Shortneing return springs is a dangerous practice.  Spring stock kits are available from Brownells, just measure the wire diameter and outside spring diameter and order the appropriate kit..  Of late almost all trigger jobs requires respringing..
