Pištola Arex Delta S 4AMP FullSize

The full-size configuration features a full-length slide and grip frame, providing maximum stability, recoil control, and magazine capacity within the Delta S lineup. As part of the 4AMP system, the pistol is supplied as a performance-oriented package including modular enhancements such as extended magazine base pads and accessory components designed to optimize handling and operational efficiency.

The platform is built on the AREX Delta architecture, utilizing a polymer frame with interchangeable backstraps, allowing ergonomic adaptation across different hand sizes. A low bore axis design and optimized slide mass distribution reduce muzzle rise and support faster follow-up shots under rapid fire conditions. The slide is machined from high-strength steel with a corrosion-resistant surface treatment for durability and service life.

The pistol operates using the SDA (Striker Double Action) trigger system, where the striker is partially pre-cocked and fully completed during trigger pull. This results in a controlled trigger stroke with a defined break while maintaining consistent safety characteristics for duty-oriented use.
