Description
The trigger is where a lot of accuracy lives or dies, and the factory unit on the Kimber Model 84 leaves plenty of room to grow. TriggerTech's Primary trigger tackles that head-on with its patented Frictionless Release Technology, which uses a free-floating roller captured between the sear and the trigger instead of the sliding metal-on-metal contact found in conventional designs. That rolling interface is what gives you a true zero-creep break and an extremely short over-travel under three hundredths of an inch, so the shot goes off exactly when you expect it to.
What Frictionless Release Technology Brings to the Model 84
Because there's no sliding friction to fight, the pull stays consistent from the first round to the thousandth. Many people describe the break as glass-rod clean, and there's a nice side effect worth knowing: the crisp release often feels around half a pound lighter than a friction trigger measuring the same weight on a gauge. The internals are hardened 440C stainless steel housed in anodized 6061-T6 aluminum, and the external parts wear a black PVD coating that shrugs off weather and hard use.
Dialing In Your Primary Trigger Pull Weight
This one runs on TriggerTech's CLKR system, letting you adjust pull weight anywhere from 1.5 to 4 pounds in one-ounce increments straight from an externally accessible set screw. A detent gives you an audible, tactile click for each step, so you're not squinting at a gauge or guessing where you landed. Set it heavy for hunting gloves and cold fingers, or bring it down light for bench and precision work.
Fit and Setup
It's a drop-in curved trigger built to fit the Kimber Model 84 and 84L, as well as the 8400 WSM and 8400 Magnum actions. Whether your rifle is chambered in 6.5 Creedmoor, .308, .270, .30-06 or one of the many other cartridges those actions come in, this trigger is a straightforward upgrade. Installation is simple compared to most trigger jobs, though having a qualified gunsmith handle it is never a bad call if you want it checked over.

Frequently Asked Questions
Which rifles does the TriggerTech Primary trigger fit?
It's built for the Kimber Model 84 and 84L, along with the 8400 WSM and 8400 Magnum actions. That covers a wide spread of chamberings on those platforms, from 6.5 Creedmoor and .308 to .270, .30-06 and beyond. As long as your rifle is one of those Kimber actions, this is a direct drop-in fit.
How do you adjust the pull weight on this trigger?
The pull weight adjusts from 1.5 to 4 pounds using TriggerTech's CLKR set screw, which is externally accessible so you don't have to fully disassemble anything. Each turn moves the weight in one-ounce increments, and a detent gives you an audible click for every step. That means you can set it precisely without a trigger gauge and know exactly where you landed.
What makes the Frictionless Release Technology different from a normal trigger?
Traditional triggers rely on metal sliding against metal at the sear, which creates creep and inconsistency. TriggerTech replaces that with a free-floating roller between the sear and trigger, so the parts roll instead of slide. The result is a true zero-creep break that stays consistent shot after shot, and the crisp release often feels lighter than the number on the gauge.
Is the Primary trigger easy to install myself?
It's a drop-in design, so installation is more straightforward than most trigger jobs and many people handle it at home with basic tools. That said, having a qualified gunsmith install it and run a function check is a smart move if you want the setup verified. Always confirm safe operation before heading to the range.
