The AM2 is one of the best feature-per-dollar carry pistols available: double-stack capacity, a real accessory rail, and encouraging published reliability. The big trade is no optic cut. If you shoot irons and want a lot of gun for the money, it earns a close look.
What the AM2 Is
Diamondback Firearms, based in Cocoa, Florida, built its name on inexpensive single-stack carry guns like the DB9. The AM2 is its move into the double-stack sub-compact class, the space the Glock 43X and SIG P365 made popular, at a much lower price.

What It Gets Right
Capacity for the size. Twelve rounds flush in a sub-compact, with a 17-round magazine in the box on the configuration we link, puts the AM2 on par with guns that cost considerably more.
A real rail. Many micro-compacts use short proprietary rails that fit only a few lights. The AM2's full Picatinny rail takes mainstream weapon lights, a big plus if the gun also serves at home.
Ergonomic details. Reviewers point to the undercut trigger guard, beavertail, flared magwell, and aggressive texture. These features used to be the domain of more expensive guns.
Glock-pattern sights. The sight dovetails accept Glock-pattern sights, so night sights and upgraded irons are easy to find, a smart choice on a gun without an optic cut.
Encouraging testing. In one widely cited independent evaluation, the AM2 had a single slide-lock hiccup on its first magazine across a 750-round test, then ran without problems. That's one test, not a decade of service history, but it's a good start.
What It Gives Up
No optic cut. In 2026, most competitors at nearby prices ship optics-ready. If you want a red dot now or later, this is the dealbreaker.
Shorter track record. The AM2 doesn't have the years of widespread carry use that the Shield or P365 lineages have. Diamondback has been making carry guns for years, but this model's long-term record is still being written.
Smaller ecosystem. Expect fewer holster options, fewer aftermarket parts, and harder-to-find spare magazines in local stores than for mainstream brands. Confirm holster availability before buying.
Slightly thicker. At about 1.09 inches wide, it's a bit thicker than the slimmest micro-compacts. Most people won't notice.
Strengths
- 12+1 flush, 17+1 extended
- Full Picatinny rail
- Undercut guard, beavertail, flared magwell
- Glock-pattern sight dovetails
- Excellent features for the price
Weaknesses
- No optic cut
- Shorter model track record
- Smaller holster and parts market
- Less brand recognition for resale
AM2 vs the Alternatives
Against the Canik MC9, the AM2 trades the Canik's excellent trigger and optic cut for more capacity and a full rail. Against the Taurus G3XL, the AM2 is slimmer and more modern in its details, while the G3XL has a longer slide and a longer track record. Our budget micro-compact guide puts all of them side by side.
Who Should Buy the AM2
- Budget buyers who want capacity and are happy with iron sights.
- Carry-plus-home-defense buyers who value the full rail for a weapon light.
- Glock-sight owners who want to reuse a sight setup they already know.

Frequently Asked Questions
Is the Diamondback AM2 reliable?
Published independent testing is encouraging. One widely cited 750-round evaluation logged a single early slide-lock hiccup and then ran cleanly. The model's long-term record is shorter than mainstream competitors', so verify your specific gun with your defensive load.
Is the AM2 optics-ready?
No. The AM2 ships with a 3-dot iron-sight slide and no optic cut. Its Glock-pattern sight dovetails make upgrading to night sights easy.
Does the AM2 use Glock magazines?
No. It uses its own Diamondback magazines. What's Glock-compatible is the sight dovetail, not the magazine.
What does the AM2 compete with?
It targets the double-stack sub-compact class made popular by the Glock 43X and SIG P365, at a lower price, and competes directly with value options like the Canik MC9 and Taurus G3XL.
