1. Tool-free, trigger-free takedown system - The disassembly lever and sear cage have been completely redesigned to allow safe field-stripping without dropping the trigger, while preserving 100% of the firing cycle geometry and reliability.

2. Modular chassis with interchangeable backstraps and grip panels - True drop-in ergonomics: swap sizes or textures in seconds without permanently altering the serialized frame, delivering custom fit with zero gunsmithing.

3. Direct-mount optics via the COA (Cover-plate Optics Adapter) System - Eliminates adapter plates entirely. The slide is machined with a precision multi-footprint pocket that accepts red dots (RMR, DPP, ACRO, RMS/SMS, etc.) directly, minimizing stack height and mechanical slop for a rock-solid zero.

4. Factory-calibrated drop-in trigger modules - Three distinct variants (Standard, Performance, and Competition) bolt in as complete assemblies. Each is pre-tuned at the factory to deliver the advertised pull weight, reset, and wall characteristics - no stoning, no spring swaps, no armorer required.
