Diamondback DB380 Gen IV Compact Pistol – .380 ACP, 2.8″ Barrel
Pros & cons
What works
- Weighs 10.6 oz unloaded — one of the lightest in its class for all-day carry.
- Nickel Boron slide coating provides superior corrosion resistance compared to standard bluing.
- 0.98-inch width is 0.1 inches slimmer than the Ruger LCP Max for deeper concealment.
- Glock-compatible sight cut allows for direct aftermarket sight upgrades without gunsmithing.
Trade-offs
- 6+1 magazine capacity is significantly lower than modern micro-compacts like the Ruger LCP Max (10+1).
- Double-action-only 5.5 lb trigger pull requires deliberate training for accuracy, unsuitable for beginners.
- No spare magazine or hard case included, adding $30-40 to the true out-the-door cost.
- Partially captured recoil spring assembly can be trickier to reassemble than a fully captured system after field stripping.

About this product
The Diamondback DB380 Gen IV Compact Pistol is a micro-compact .380 ACP striker-fired pistol engineered for discreet, reliable concealed carry. Its design prioritizes corrosion resistance and a consistent mechanical trigger action, making it a purpose-built tool within the subcompact market, sitting firmly between pocket pistols and larger micro-nines.
What is the Diamondback DB380 Gen IV Compact Pistol used for?
The DB380 Gen IV is designed for primary or backup concealed carry where discretion and reliable mechanical function override higher capacity. Its 0.98-inch width and 6+1 capacity make it exceptionally concealable for all-day wear, and the double-action-only striker system provides a deliberate, consistent trigger pull for defensive use without an external safety. The Nickel Boron-coated slide and 410 stainless barrel offer enhanced corrosion resistance against sweat, a critical feature for holstered, body-worn carry.
How does the DB380 Gen IV compare to the Ruger LCP Max?
The DB380 is mechanically simpler and slimmer, while the Ruger LCP Max offers significantly more capacity in a slightly wider frame. The DB380's 2.8-inch barrel and 4.51-inch sight radius provide a theoretical ballistic edge over the LCP Max's 2.8-inch barrel with a shorter sight radius, aiding in sight alignment. However, the Ruger LCP Max holds 10+1 or 12+1 rounds, making it better for shooters prioritizing round count; the DB380's 6+1 capacity is better for those valuing a thinner 0.98-inch profile and the consistency of a mechanical double-action-only striker system over a pre-cocked one.
What does it weigh and what are the dimensions?
The DB380 Gen IV weighs 10.6 ounces unloaded and measures 5.22 inches long, 3.82 inches high, and 0.98 inches wide. The 2.8-inch barrel has a 1:10 right-hand twist, standard for stabilizing common .380 ACP defensive loads. These dimensions, particularly the sub-1-inch width, contribute directly to its concealability, allowing it to disappear in a pocket holster or minimal inside-the-waistband rig, unlike bulkier options like the Stevens 334 Rifle designed for entirely different applications.
Who is this NOT for?
This pistol is not for shooters seeking high-capacity defense, recreational range use, or those who struggle with heavy trigger pulls. The 6+1 capacity is limiting compared to modern micro-9mms, and the 5.5-pound double-action-only pull can be challenging for new shooters to master, making it a poor choice for high-volume practice. If your primary use involves hunting or clay sports, a dedicated shotgun like the Stevens 555 Sporting O/U is a far more suitable tool.
What's in the box?
The factory package includes the pistol, one 6-round magazine, a polymer magazine floor plate, a cable lock, and the owner's manual. Unlike some competitors, it does not include a spare magazine or a hard case, offering a no-frills delivery focused on the core firearm. The manual contains essential disassembly instructions and warranty information, which should be reviewed before first use to understand the takedown procedure for the partially captured, all-steel recoil assembly.
Is the Diamondback DB380 Gen IV worth it at $296.99?
At $296.99, the DB380 Gen IV presents a clear value proposition based on its corrosion-resistant construction and specific mechanical design. You are paying for a reliable, no-safety, DAO micro-pistol with premium slide coating and Glock-compatible sight cuts, not for accessories or high capacity. If your sole requirement is the thinnest, most mechanically straightforward .380 for deep concealment, it's worth the price; if you want higher capacity or a lighter trigger, allocate your funds elsewhere.

Frequently asked questions
- Is the DB380 Gen IV compatible with Glock sights?
- Yes. The slide is cut for Glock-style rear sights, specifically the Glock 42/43 pattern. This allows for direct installation of a vast aftermarket selection of steel, fiber-optic, or tritium night sights from brands like Trijicon or AmeriGlo without machining.
- Does it fit a Ruger LCP holster?
- No, it will not reliably fit a holster molded specifically for a Ruger LCP or LCP Max. The DB380's slide profile and dimensions, particularly its 0.98-inch width versus the LCP Max's 1.08 inches, require a holster designed for its exact frame. Use a universal pocket holster at your own risk, or purchase a dedicated model from a holster maker like Vedder or DeSantis.
- How long does shipping take to an FFL?
- Standard processing for in-stock firearms is 1-2 business days before shipment. Once shipped, transit time to your selected Federal Firearms License (FFL) dealer is typically 3-7 business days via ground service. You must contact your chosen FFL in advance to provide their license and coordinate the transfer, which can add 1-3 days for paperwork processing.
- Can I return it if it doesn't function?
- New firearms in unfired condition with all original packaging can be returned within 30 days for a full refund, minus a 15% restocking fee. If the firearm has a mechanical defect, you must contact Diamondback's warranty service directly for repair or replacement; do not attempt to ship a firearm directly back without an approved Return Merchandise Authorization (RMA) number and specific carrier instructions.
- Does this work with +P .380 ACP ammunition?
- Diamondback does not recommend or certify the DB380 for use with +P or +P+ .380 ACP ammunition. The pistol's all-steel, partially captured recoil spring system is designed for standard pressure rounds. Firing +P ammunition may accelerate wear, void the warranty, and increase perceived recoil beyond the pistol's design parameters.
