About this product
The Diamondback DB9 Gen IV is a micro-compact 9mm pistol engineered for concealed carry, featuring a 3.10-inch stainless steel barrel, OD Green polymer frame, and 6+1 capacity. It weighs 13.40 oz unloaded and measures 5.73 inches in overall length, prioritizing discreet carry and corrosion resistance with its black nitride slide finish. Built for daily use, it balances durability with straightforward controls.
What is the Diamondback DB9 Gen IV used for?
The DB9 Gen IV is designed for concealed carry and everyday personal defense. Its compact 5.73-inch length and 13.40 oz weight make it ideal for pocket or inside-waistband holsters, while the 9mm chambering provides adequate stopping power in a minimal package. This pistol suits urban environments where discretion is paramount.
How does the Diamondback DB9 Gen IV compare to the Ruger LC9?
The DB9 Gen IV is 2.3 oz lighter and 0.4 inches shorter than the Ruger LC9, favoring deeper concealment. However, the LC9 offers a smoother trigger pull and better aftermarket support, making it superior for shooters prioritizing customization. For raw portability, the DB9 Gen IV excels.
What does it weigh and what are the dimensions?
Unloaded weight is 13.40 oz, with an overall length of 5.73 inches and barrel length of 3.10 inches. The height is 4.0 inches, and width is 0.88 inches, contributing to its slim profile. These dimensions ensure it fits standard micro-compact holsters and pockets without printing.
Who is this NOT for?
This pistol is not for high-volume shooters or those needing extended capacity. With only 6+1 rounds, it falls short for duty use or competitive shooting. Recoil is snappy due to its light weight, so beginners or those with hand strength issues might struggle. Consider the Stevens 334 Rifle for more stable platforms.
What's in the box?
The box includes the pistol, one 6-round magazine, a cable lock, and owner's manual. No additional backstraps or cleaning kits are provided, keeping the package minimal. Expect to purchase a holster and extra magazines separately for full usability.
Is the Diamondback DB9 Gen IV worth it at $282.99?
At $282.99, it's a budget-friendly option for a dedicated concealed carry piece. You're getting a functional 9mm with corrosion-resistant coatings, but trade-offs include limited capacity and a basic trigger. For similar pricing, the Stevens 555 Sporting Compact offers a different type of reliability in a shotgun platform.
