GRITR Optic Plate for Walther PDP 2.0 - RMR Footprint Adapter

In this review the GRITR Optic Plate is evaluated as a simple, durable adapter for Walther PDP pistols fitted with the 2.0 optic plate mounting system. The bottom line: if you need a solid, no-nonsense way to mount RMR-footprint optics such as Trijicon RMR or Holosun models to a Walther PDP, this plate delivers predictable fit and long-term durability thanks to machined 6061-T6 aluminum and Type III anodizing. It includes the screws, a short T10 Torx wrench, and a small protective case, so installation and carry are straightforward for most owners.

Key Features

• Compatibility: Designed specifically for Walther PDP models with the 2.0 optic plate mounting system, ensuring the plate aligns with the factory cut.
• RMR Footprint Support: Accepts optics using an RMR footprint, letting shooters mount Trijicon RMR, SRO, or compatible Holosun 407C/507C variants.
• Durable Construction: Machined from 6061-T6 aluminum and finished with Type III anodizing for corrosion resistance and surface hardness during frequent use.
• Complete Hardware: Ships with black-oxide alloy steel T10 Torx screws and a short Protanium steel T10 L-wrench to make installation accessible to most users.
• Protective Case: Comes with a small case that doubles as storage for spare parts, tools, or a lens cloth to keep accessories organized.
• Warranty: Backed by an UNLIMITED GRIT Lifetime Warranty that covers defects and replacement (does not cover loss or deliberate damage).

Who It's For

The GRITR Optic Plate is best for Walther PDP owners who want to fit a compact red dot with an RMR footprint and value a rugged aluminum adapter that comes with installation hardware. It suits competitive shooters who swap optics for a tailored sight picture and owners who prefer a metal plate over polymer alternatives for longevity and stiffness.

Shooter types who should look elsewhere include owners of non-PDP pistols or those using optics that do not follow the RMR footprint. Also, if you require brand-specific engraved mounts or an optic-specific shim kit, this universal adapter may not address every fine-tuning need noted by some users.

Pros & Cons

Cons

• Some mount types and specific RMR-style bases may not be universally compatible, so check optic mounting footprint carefully.
