Description
The Timney Featherweight 601 is a self-contained replacement trigger built specifically for the Ruger Model 77 with a tang safety, including the original Mark 1 flat-bolt actions. If you've spent any time behind one of these classic bolt guns, you know the factory trigger can feel heavy and gritty with a fair bit of creep. This unit swaps all of that out for a clean, predictable break that makes a real difference the second you touch it off.
Each one is precision machined and hand-fitted, then individually tested and calibrated by hand before it ships. The housing is a lightweight alloy paired with machined and hardened steel working surfaces, so it holds its adjustments and shrugs off wear. It comes set from the factory at right around 3 pounds, which is a great all-around weight for hunting and range work, and it's fully adjustable for pull weight, sear engagement (creep), and overtravel so you can tune the feel exactly how you like it.
What the Timney 601 Does for Your Ruger 77
A better trigger is one of the most noticeable upgrades you can make to any rifle. Cleaning up the slack and inconsistency of a factory trigger helps you break the shot without disturbing your aim, and that translates to tighter groups downrange. The curved black shoe feels natural and keeps the classic look of the rifle intact.
Installing the Featherweight 601
Worth knowing up front: the tang safety Model 77 is more involved than a typical drop-in job. Timney notes the install runs roughly one to two hours and calls for removing a good amount of wood from the stock, plus some minor fitting to get the safety functioning crisply. Folks handy with hand tools and a Dremel manage it at home, but if you'd rather not carve on your stock, a gunsmith can knock it out quickly. Made in the USA and backed by Timney's long reputation, this one earns its keep once it's dialed in.

Frequently Asked Questions
Will the Timney 601 fit my older Ruger 77 with a tang safety?
Yes. This trigger is designed for the Ruger Model 77 with a tang safety, and that includes the original Mark 1 flat-bolt actions from the pre-1971 era through the tang safety models. It will not fit the later Mark II or Hawkeye rifles, which use a different design. If your rifle has the safety on the tang behind the bolt, this is the right unit.
Is the Timney 601 a true drop-in trigger, or does it need fitting?
On the tang safety Model 77 it's more involved than a typical drop-in. Timney says installation takes about one to two hours and requires removing a good amount of wood from the stock, along with some minor fitting to get the safety working crisply. Many owners with basic hand tools tackle it themselves, but a gunsmith is a smart call if you'd rather not modify the stock.
How light can I set the pull weight?
The 601 arrives calibrated at around 3 pounds and is adjustable down to about 1.5 pounds and up to roughly 3.5 pounds. You can also fine-tune sear engagement and overtravel. Take your time with the adjustments and always confirm the trigger and safety function correctly before shooting.
What's the real benefit over the factory Ruger trigger?
The factory trigger on these rifles tends to be heavy with noticeable creep. The Timney gives you a clean, consistent, repeatable break that lets you fire the shot without disturbing your point of aim, which usually tightens up your groups. It's one of the most cost-effective accuracy upgrades you can make to the rifle.
