The AREX Defense Rex Delta pistol comes to U.S. shores from Slovenia and is a double-action-only pistol chambered in 9 mm Luger that is sized appropriately and enhanced for concealed carry. Similar in size and design as Glock’s G19 pistol, the AREX Defense Rex Delta is privy to an aftermarket of accessories that will further bolster its worthiness to consumers.

Built on a black polymer frame, the Rex Delta pistol provides its operator with thoughtful ergonomics throughout. Replaceable backstraps allow a custom fit without custom pricing. The gun’s magazine release button is a bilateral design that allows users to engage from either side. AREX Defense provides an enlarged trigger guard along with texturing to accommodate myriad shooting styles and situations. An accessory rail along the dustcover is provided, too.

Feature-rich and modestly priced, the ReX Delta ships with two proprietary magazines from Mec-Gar. The extended unit allows for up to 17 rounds and a lengthened baseplate is provided to achieve an additional two rounds of capacity. A loaded chamber indicator sits topside and a red striker-status indicator is found at the slide’s rear. AREX Defense provides a Nitride finish that renders the steel slide of the Rex Delta in a matte black finish.
