Ruger m77 trigger question


July 30, 2012, 10:50 AM
I bought a older Ruger M77 MKII. It is roughly a 1992 or 93 model. I really like the rifle but, the trigger pull seems heavy. Is there a way to adjust the trigger or do I need to purchase a new trigger that can be adjusted? If I do need to purchase a new trigger what should I buy? Thx for the help in advance.

Ruger 77 MKII rifle trigger is not adjustable. It can be massaged by a gunsmith, but the easy fix is to simply replace it. A replacement will get you an overtravel adjustment too. I like the Timney replacement trigger for that model, there are others.

It's even offered in variants for RH and LH versions of the Ruger 77 MKII rifle.

I have had the same trigger in my ruger for 15 years and it has been a very good trigger. Mine has been set to its minimum weight for the 15 years .

My wife and I have 2 Ruger M77's, Mk II. Hers is a .243win Ultralight, and mine is a .270win (which she loves, and keeps asking if I'll give to her). I decided to replace the .270 trigger with a Timney, as it was pretty heavy, and had a little "creep."

Installation is pretty simple, you may have to gently file/stone a little metal to get safety engagement set up, but that's all. The Timney was adjusted to 3lb.-4oz., and it is a "thing of beauty and a joy forever!" -No creep, no overtravel, a clean break, consistent shot after shot. Just put a little pressure on the trigger, and it releases without felt motion.

My wife tried my .270 on the range the first time I took it out to test the Timney, and 2 weeks later I was installing another one in her .243! ;)

I bought a Timney for mine, but IMO the parts had too much clearance on the pins and I therefore didn't trust them to last in a safe condition. I took them right back out and put the horrendous OEM parts back in.

The post 1992 MK-II's do not have adjustable triggers. From the factroy they vary from acceptable to pretty bad. Basically inconsisent. The 2006 and newer Hawkeye's are much better in my opinion. Not match grade, but a perfectly acceptable hunting trigger.

If it were my gun I'd try to stay with the factory trigger. They, and the older style Winchester trggers, are the most bulletproof, rugged triggers made. They can be made better with a triggerspring replacement. Try

With a little polishing of the trigger surfaces along with a lighter spring you can not only have one of the most rugged reliable triggers, but one that is pretty good as well. It is not rocket science, just google "Ruger 77 trigger adjustment" and you will find lots of instructions and diagrams explaining how to do it. If you are not comfortable doing it, then take it to a gunsmith. You may not need anything but a replacement spring to get it where you want. I'd try that first.
