Description
The Timney 641C is a drop-in replacement trigger designed for Gen I Ruger American Centerfire rifles equipped with a two-position safety, as well as Glenfield Model A rifles. It is also compatible with left-handed actions, so that compatibility needs to be noted: this trigger does not work with left-handed actions.
The core appeal of this trigger is adjustability without requiring a gunsmith. Pull weight is factory set at 3 pounds and can be tuned across a 2-to-4-pound range, giving a hunter or range shooter room to find a weight that suits their grip and shooting position without pushing into territory that risks unintended discharge. Sear engagement is adjustable as well, which lets you refine the amount of travel before the trigger breaks — useful when dialing in a consistent, repeatable feel for precision work.
The two-position safety mirrors the layout of the factory Ruger safety, so there is no relearning the manual of arms after installation. The trigger itself uses a curved shoe, which distributes finger pressure across a wider contact arc than a straight shoe and gives some shooters a more natural reference point for consistent finger placement shot to shot.
Timney manufactures the trigger in the United States and backs it with a lifetime warranty — they will repair or replace a defective trigger at no charge. Installation is tool-friendly and designed to be completed without professional fitting, making it a practical upgrade for a shooter who wants more control over their trigger characteristics without sending the rifle out for work.
