Full Product Overview

Stop letting open emitter optics collect dust, lint, and rain inside your carry rig. The C&H Precision Optic Adapter Plate (SKU: TAUR-G3C-509T) bridges the gap between your factory optics-ready handgun and premium enclosed cross-bolt optics. Designed explicitly to replace standard factory adapter plates on the Taurus G3 and G3c T.O.R.O. (Taurus Optics Ready Option) series slides, this aftermarket modification offers an ultra-precise, low-bore-axis fitment that minimizes structural movement and holds zero through hard duty use.

Every plate is meticulously CNC-machined at C&H Precision's state-of-the-art facility from high-strength 6061 aircraft-grade aluminum and coated in a MIL-SPEC Type III Hard Anodized black finish. This design yields an exceptionally lightweight plate that resists corrosion without introducing excess height or weight to your reciprocating slide layout. Complete with stainless steel mounting hardware and a single-use vial of VC3 Vibratite thread locker, this package includes everything required to achieve a permanent, torque-reliable optic seat that won't back out under repetitive recoil forces.

Storefront Frequently Asked Questions

Q: Will this adapter plate fit a standard base model Taurus G3 or G3c?

A: No. This adapter plate is engineered strictly for the T.O.R.O. (Taurus Optics Ready Option) versions of the G3 and G3c pistols. Your slide must feature the factory-milled optic cut and removable cover plate to use this adapter system.

Q: Can I use this plate to mount a Holosun EPS or EPS Carry sight?

A: No. While the Holosun EPS series utilizes an enclosed system, it uses the smaller Holosun K-series footprint. This specific plate features the proprietary cross-bolt clamping rails engineered exclusively to fit the larger Holosun 509T footprint.

Q: Do I need to buy separate screws to mount the plate to my Taurus slide?

A: No, everything you need is included. The package comes complete with two stainless steel plate mounting screws tailored for your T.O.R.O. slide threads, along with a packet of premium VC3 thread locker to ensure a secure, vibration-resistant mount.
