The Arex Delta M Gen 2 Pistol

Arex Delta M Gen 2 overview and basic specs

The video introduces the Arex Delta M Gen 2, a Slovenian-made 9mm striker-fired pistol supplied in a hard shell case. The pistol ships with two metal magazines, one 15-round and one 17-round, and uses a 4-inch barrel. Listed overall length is 7.24 inches, with a measured length of about 7 inches. Thickness is 1.18 inches, making it relatively slim for its size. The unloaded weight is given as 19.1 ounces and 21.6 ounces with a magazine inserted. The review focuses on confirming these technical specifications and examining the features visible on the pistol as it comes from the factory.

Slide, sights, frame, and ergonomics

The barrel protrudes slightly from the front of the slide, which carries a single white-dot front sight and blacked-out rear sights to aid quick target acquisition. The slide has angular cuts at the front and along the top, as well as pronounced front and rear slide serrations that support various racking techniques. The polymer frame includes a three-slot Picatinny rail under the dust cover for mounting accessories. There are grooves on the front of the trigger guard and on the underside of the frame to accommodate different support-hand positions. A slight undercut at the trigger guard allows a higher grip on the pistol, intended to help with control and follow-up shots.

Controls, grip texture, and magwell

The trigger features an integrated safety tab and a defined take-up before reaching a distinct wall and a crisp break. The reset is short, followed by a small additional pull. The pistol has ambidextrous slide releases that can be actuated from either side, as well as an ambidextrous magazine release, making it usable for both right- and left-handed shooters. The rear of the firing pin is painted red and visible when the pistol is ready to fire, disappearing when the trigger is pulled. Grip texturing extends high on the frame and continues around the sides, front, and backstrap with a moderately aggressive pattern. The magwell is slightly flared to assist with magazine insertion without being overly bulky.

Verifying dimensions and weight

The reviewer measures the pistol to compare against the published specifications. Using a measuring tool, overall length comes in at about 7 inches, slightly under the listed 7.24 inches, likely due to how the beavertail and grip are referenced. Height without a magazine is about 4.5 inches, while the listed 4.7-inch height appears accurate when a magazine, particularly the extended option, is inserted. Width is confirmed at approximately 1.14 inches, matching the manufacturer’s claim and reinforcing the pistol’s relatively slim profile. On a scale, the unloaded pistol weighs 1.19 pounds, which converts to the stated 19.1 ounces. With a magazine inserted, the scale reads 1.36 pounds, or about 21.7 ounces, essentially matching the quoted 21.6 ounces.

Trigger pull testing and results

Trigger pull is tested with a gauge to quantify the feel described earlier. Bracing the pistol and pulling straight back on the trigger, the first reading shows approximately 4.41 pounds of pressure. A second pull registers about 5.07 pounds, with the observation that the gauge may have caught on the trigger safety fin. A third attempt yields around 4.6 pounds, though there is a slight wobble on the trigger during the pull. Across multiple measurements, the trigger consistently falls in the 4- to 5-pound range. This aligns with the impression of a duty-style trigger that has a defined wall, a crisp break, and a reset suitable for controlled shooting.

Case, magazines, and included accessories

Attention shifts to what is included in the Arex Delta M Gen 2 hard shell case. The case itself can be locked through a dedicated point, offering an additional layer of security when a safe is not immediately available. Inside, the pistol comes with the 17-round magazine featuring an extended baseplate that protrudes below the grip when inserted, providing extra capacity and a full firing grip. A basic cleaning kit is included, with threaded rods that can be assembled for cleaning the bore, though different rod sizes are shown. The standard 15-round magazine is also present, giving users two capacity options out of the box.

Interchangeable backstraps and fit

The pistol includes multiple interchangeable backstraps to adjust grip size and shape. Swapping backstraps changes the distance between the rear of the grip and where the middle finger rests, which can better accommodate larger hands or longer fingers. One backstrap option has a more pronounced hump that fills the palm, while another is closer to a straight profile for a slimmer feel. These options allow the shooter to fine-tune the grip to personal preference, improving comfort and control. The texturing on each backstrap matches the rest of the grip, maintaining a consistent level of traction regardless of which insert is installed.

Closing thoughts on the Delta M Gen 2

The review concludes by noting that the Arex Delta M Gen 2 largely matches its published specifications for dimensions, weight, and trigger pull. The pistol offers a slim 9mm compact platform with ambidextrous controls, a moderately aggressive textured grip, interchangeable backstraps, and both 15-round and 17-round metal magazines. The hard shell case, cleaning kit, and lockable design add practical value for storage and transport. Viewers are invited to share their own experiences with the Arex Delta M Gen 2 and to ask questions in the comments, while the presenter expresses interest in taking the pistol to the range after the review.
