Description
The Diamondback AM2 sits in an interesting sweet spot in the sub-compact market. It's sized somewhere between a Glock 26 and a Glock 19, measuring just over an inch wide, with a grip that actually gives you something to hold onto without making the gun difficult to conceal. The flush-fit 12-round magazine keeps the profile tight for IWB carry, while the included 17-round extended magazine with grip sleeve transforms it into a home defense-ready platform. That kind of versatility in one box is genuinely hard to find at this price.
What Makes the AM2's Build Stand Out
At the core of this pistol is a serialized metal fire control chassis housed inside the polymer frame. The slide rails on that chassis are noticeably beefy, running thick enough that multiple reviewers have called them out specifically, which translates to a tight, consistent slide-to-frame fit. The stainless steel slide wears a QPQ black nitride finish for glare-free durability and corrosion resistance, with aggressive front and rear cocking serrations that are easy to grab with or without gloves. The stainless steel barrel runs a 1:10" right-hand twist, and a small chamber viewing port on top gives you a fast visual chamber check without manipulating the slide.
Grip ergonomics on the AM2 are one of its stronger selling points. The stipple texture runs across the front strap, backstrap, and both side panels, and it's aggressive enough to stay put in sweaty conditions without being uncomfortable for all-day carry. A slight undercut behind the trigger guard lets you ride the gun higher in your hand, and the built-in beavertail keeps the slide off your web. The magazine release sits flush with the frame to prevent snag on the draw and is reversible for left-handed use.
The DBAM29's Sights and Customization Options
Diamondback fitted the AM2 with metal 3-dot sights machined to Glock-pattern dimensions, meaning the entire aftermarket ecosystem of Glock-compatible night sights, fiber optics, and suppressor-height sights drops right in without any gunsmithing. The rear sight is also drift adjustable for windage at the factory. The Picatinny rail forward of the trigger guard is a generous cut that accepts most standard weapon lights and lasers, which is a feature a lot of sub-compacts in this category skip entirely. Fieldstripping follows the same process as a Glock and requires no tools, with a captive recoil spring assembly that makes reassembly straightforward.

Frequently Asked Questions
What holsters fit the Diamondback AM2 DBAM29?
The DBAM29 has a dedicated holster footprint, and Diamondback has worked with several manufacturers to ensure carry options are available. Brands like Crossbreed, Dara Holsters, Urban Carry, and Remora all make IWB options specifically for this model. Because it is not Glock-pattern dimensionally, you'll want to search specifically for DBAM29-compatible holsters rather than assuming Glock 26 or 43X holsters will fit.
Does the Diamondback AM2 accept aftermarket sights?
Yes. Diamondback machines the slide to accept Glock-compatible sights, so you have a very wide selection of aftermarket options including night sights, fiber optic fronts, and suppressor-height sets. The rear sight is also drift adjustable at the factory for windage. This is one of the more practical decisions Diamondback made with the AM2, since it keeps upgrade costs low.
How does the AM2 compare in size to a Glock 43X or Glock 26?
The AM2 sits roughly between those two in overall size, with a barrel length and footprint closer to the Glock 43X but a slightly wider grip due to the double-stack magazine. The overall width comes in at 1.09 inches, making it thinner than a Glock 19 but a touch wider than the slimline 43X. For most carry purposes it fits the same general niche.
Can I use the 17-round magazine with the AM2 for daily carry?
You can, though the 17-round magazine extends well below the grip frame and is best suited as a range magazine or a home defense setup rather than IWB carry. The flush-fitting 12-round magazine is the better choice for concealed carry since it keeps the overall height compact. The 17-round mag ships with a grip sleeve that fills the gap between the frame and the extended baseplate, which helps with comfort during range sessions.
Is the Diamondback AM2 reliable enough for everyday carry?
Multiple independent reviews and extended range tests have put the AM2 through hundreds to over a thousand rounds without reported malfunctions. The QPQ-treated stainless steel barrel and slide offer solid corrosion resistance for a gun that gets carried daily and exposed to sweat and humidity. Like most striker-fired pistols, the action may feel a bit stiff right out of the box and loosens up with use.
What is the difference between the 12-round and 17-round magazine configurations?
The flush-fit 12-round magazine sits even with the bottom of the grip frame, keeping the pistol as compact and concealable as possible. The 17-round extended magazine adds five rounds and comes with a grip extension sleeve for a more comfortable full-hand hold. Both are double-stack magazines, and both are included in the box with this model.
