The EAA Witness Full Size Steel Combo delivers classic CZ-75 ergonomics with modern manufacturing precision. It’s built for shooters who value a solid steel frame, a crisp single-action trigger, and the versatility of two calibers in one package. We’ve stocked this combo since January 2026, and it consistently brings repeat customers back for its reliable performance and tangible quality.
Key Features
- Convertible Steel Frame Platform: Includes both 9mm and .40 S&W slides and barrels. Swap calibers in minutes for range flexibility.
- All-Steel Construction: Full-size steel frame and slide provide a balanced, recoil-absorbing heft that enhances control.
- Precision-Machined Fit: Components are machined to tight tolerances for a smooth, solid feel. One customer returned it citing it was ‘too tight,’ which we traced to an aftermarket frame. It runs flawlessly on OEM parts.
- Excellent Trigger System: Features a clean-breaking single-action mode and a consistent double-action pull, right out of the box.
- High-Capacity & Optics-Ready: Ships with 16-round (9mm) and 12-round (.40 S&W) magazines. The slide is pre-milled for mounting a red dot sight.

Frequently Asked Questions
What comes in the combo box?
The package includes the steel frame, two complete slide assemblies (one in 9mm, one in .40 S&W), two matching barrels, two magazines (16rd 9mm, 12rd .40), and all necessary tools for the caliber conversion.
Is this compatible with CZ-75 magazines?
Yes. The EAA Witness uses the same magazine pattern as the CZ-75, so a wide range of aftermarket and OEM CZ magazines are compatible, offering great flexibility for parts and accessories.
How difficult is the caliber conversion?
It’s a straightforward process. You simply lock the slide back, remove the slide stop lever, swap the entire slide assembly, and reinsert the lever. The process takes under a minute and requires no additional fitting.
