My M77 shoots well, but it would shoot a lot better if I could get the trigger down to 2-3 lbs. Currently it's a crisp 5 1/2 lbs give or take. Is there a drop in, aftermarket option or a way to improve the OEM trigger?

I installed a Timney in mine 40 years ago, but don't know if they still make that model. The original trigger can likely be fine tuned, but not sure about minimum weights.


Too close for irons, switching to scope...

Rifle Basix makes a sear which is very easy to swap out with the factory original. It should easily get you between 2-3 pounds.

Thanks so much barm, I was hoping there would be something like this available. I also found that there is a replacement spring from Ernie the Gunsmith. Not sure if I should get both or just the sear.

Timney still makes a trigger, but I've read that it takes some inletting to make it fit. I'd like to avoid that.

When I used the sear I also used a lighter trigger spring to get a pull weight close to 2 lbs. I don't have the rifle anymore, but I still have the sear. Let me know if you are interested in a used one to save a few bucks.

One caution about the Timney unit, the trigger blade is wider than the OEM unit, so you have to mill out the rectangular slot on the top of the alloy trigger guard. Those trigger guards are brittle and easy to crack if you try to take too much material at once. I know this because it happened to me. Twice.

And, yes, the Timney unit does require the removal of some stock material.

I've tweaked both of my tang factory triggers down to about 3# and 3 1/2# respectively. I prefer 2 1/2, but they will do.

I'm not shooting little critters nor beyond 400 yards.

Still, one of these days I'll swap out the sears and springs. No hurry, unless I die first.... smile

I also have used Rifle Basix sears and lighter springs. It was easy and yielded good triggers each time.

The tang safety Ruger trigger are fully adjustable for sear engagement, weight of pull, and overtravel. A 2 1/2 pound trigger is usually easily achievable. GD

I use this for reference. All my Ruger M77s have 2.5 lb triggers, with 0 creep, using this method. Click on "drawing", in the 4th paragraph.....and "additional pictures and comments", at the bottom...for more detail.

When finished, I test the integrity of the trigger by slamming the bolt shut with the palm of my hand.....very smartly. None of the triggers will slam fire. I have alot of confidence in them.

All of these instructions and pictures have nothing to do with the tang safety models which already have adjustment screws and are fully adjustable. GD

GD, aren’t some of the screws epoxied on the later tangers due to a safety recall? I read something about that, not exactly sure what Ruger actually did to them. Mine has the mod, whatever it was (letter T etched under bolt handle).

I have never seen an epoxy which would not succumb to the use of a heat gun. It is plain that Ruger learned that the adjustments, though they were simple enough, were too complex for the owner's to deal with, so they changed the design. I don't think this was necessarily a bad thing, although I liked the tang safety. GD
