Ready To Shoot When It Arrives
Why Choose TrueZero
- Faster aiming in low light.

- Better precision at extended range.
- Improved shooting ability in rapid and slow fire.
- Similar red-dot sight picture as a tactical carbine.
- Improved performance for shooters with impaired vision.
The strongest handgun RDS mounting system on the market is available now.
The TrueZero RDS (Red Dot Sight) attachment plate is machined from hardened chromoly steel and secured with three tapered-head T20 M4 screws. When properly torqued to specification and installed with red threadlocker, a TrueZero plate will not shoot loose. A mechanical lock plus screws secures the plate to the slide. Removed and properly reinstalled, it returns to zero every time.
Switching between RMR, Holosun K / RMSc, DPP, and ACRO footprint red dots simply means changing a plate. Every plate is available with or without a rear sight dovetail, providing a windage-adjustable backup sighting system if the optic fails. TrueZero is normally configured with back-up iron sights in the lower 25% of the optic window.

Train With Confidence
Master Your Red Dot
A properly selected, installed, and maintained optic provides the greatest benefit when paired with regular, realistic practice.
Before Installation
- Make sure the optic is in good working order and install a fresh, high-quality battery.
- Test-fit the optic, plate, screws, and T20 driver before applying threadlocker or torque.
- Confirm that the optic sits flush on the plate, the plate fits the slide, and the mounting screws fully engage.
Plate Installation
- Degrease the three supplied M4 plate screws and the threaded holes in the slide.
- Install the plate using the supplied tapered-head M4 screws with Red Loctite® 271.
- Torque each plate screw to 30 in-lbs.
- Do not allow excess threadlocker to enter the slide.
NOTE: To remove or replace the optic plate, apply heat with a propane torch to the three mounting screws to soften the Red Loctite® 271 before removal. Failure to apply heat may damage the T20 Torx® screw sockets.
Optic Installation
- Degrease the optic mounting screws and the threaded holes in the TrueZero plate.
- Apply Blue Loctite® 243 to the optic mounting-screw threads.
- Torque the optic mounting screws to 18 to 20 in-lbs.
- Confirm that the screws fully engage the mounting-plate threads.
- Allow the threadlocker to cure for 24 hours before firing.
Maintenance
- Keep the optic lens clean using an appropriate lens wipe.
- Use a lens-safe anti-fog treatment when needed.
- Replace the battery annually, regardless of the advertised battery life.
- Check the mounting screws before each range session to confirm they have not loosened.
Zeroing & Carry
- Zero the optic between 10 and 25 yards based on the intended use of the handgun.
- Many shooters find a 15-yard zero provides a practical balance for general defensive use.
- A polymer shim may be used when an optic does not have sufficient internal adjustment to zero.
- Use a holster that does not contact or impact the optic during reholstering.
