The Arex Delta M Gen 2 is a compact 9mm semi-automatic pistol with a polymer frame and a gray finish. It has a 4-inch barrel and a 7.1-inch overall length, and it weighs 24.7 ounces. The striker-fired action includes a trigger safety. The pistol holds 15+1 rounds and comes with two 15-round magazines.

A compact frame with a four-inch barrel suits concealed carry and everyday defensive use, where the balance between size and sight radius matters. The 15+1 capacity suits a shooter who wants more rounds before a reload. Standard sights and no optic-ready slide keep the setup simple. Buying it works like any handgun: a dealer, Form 4473 and a background check, and some states add permits or waits at pickup.
