The Arex Delta M is a striker-fired 9mm from Global Trade Defense with a 4-inch barrel, 17-round capacity, and a gray finish. It's a service-size pistol aimed at the same market as the Glock 17 and Sig P320 — carry, home defense, and range use.

Features 

The Delta M uses a striker-fired action with a consistent pull weight across the stroke. The slide has a black nitride finish for corrosion and wear resistance. Interchangeable backstraps let you adjust the grip to fit different hand sizes without swapping the whole frame. An accessory rail on the dust cover accepts lights and lasers in the standard format.

Most owners lead with ergonomics. The grip feels natural at initial handling, and the backstrap options let shooters with smaller or larger hands get a comfortable fit. Accuracy reports are generally solid — people coming from other 9mm service pistols find the transition straightforward.

Build quality and price relative to capacity are the consistent positives. Getting 17 rounds and decent construction at the Delta M's price point gets repeated attention, especially compared to established brands at higher price points.

The trigger comes up as a mixed point. Some owners are satisfied; others find it less crisp than they'd prefer and look at aftermarket options. Parts and accessory availability is thinner than it is for Glock or Sig, which matters more to some buyers than others.

Weight runs a bit heavier than some comparable polymer-frame pistols. Not a dealbreaker for home defense, but it comes up when owners consider it for everyday carry.
