Product Description


Diamondback Firearms is proud to present the DB9, a micro-compact 9mm pistol made entirely in the USA. Designed with safety in mind, the DB9 features a "ZERO-Energy" striker firing system with a mechanical firing pin block, a steel magazine catch to secure a sheet metal magazine and real windage-adjustable sights, all in a lightweight pistol. A steel trigger with dual connecting bars allows for a crisp, smooth, trigger pull. The DB9 features a FEA (Finite Element Analysis) designed slide and barrel that is stronger than any comparable firearm, resulting in durability with less felt recoil, and the absence of removable pins or tools makes field stripping easier than ever. The slide, barrel, and internal parts are coated to resist corrosion, making this pistol a lifetime investment.

Notice: Due to potential cyclical problems involving recoil energy, Diamondback Firearms does not recommend the use of any 9mm SAMMI Specification ammunition in bullet weights exceeding 124 grain.

The use of +P, +P+, reloaded, or NON-SAMMI Spec ammunition will void the firearms warranty.

DISCLAIMER: Crimson Trace Corporation© DB .380 specific laser mount is not designed for the DB9. Use of the CTC laser mount on the DB9 will void the manufacturers warranty.

Firearms Policy

How to Buy a Firearm or Ammunition

Federal firearms laws prevent the sale of a weapon from Red Dot Arms, LLC. directly to an individual in another state (we are located in Illinois). We must ship your firearm directly to an FFL Dealer near you. The steps to follow are:

  1. Order your firearm online using our secure shopping cart. If you know the FFL dealer you are going to use at time of order placement (not a requirement) enter his name and address into the 'Ship To' field.
  2. Find an FFL dealer near you that will accept the transfer of the firearm for you. Most sporting goods stores and pawn shops will provide this service for a small fee. Also, gun clubs, shooting ranges, etc. may provide this service to you. If you don't know which FFL dealer to use in your area, put a comment in your order and we will help you locate one near you. We have access to a large list of dealers in the USA that will gladly handle a transfer for you. Most dealers charge around $25 for a transfer. You must confirm the transfer with your local FFL dealer in advance.
  3. Next, have the dealer send us a copy of his signed license if we don't already have it on file. To check whether a license is on file, contact us. Please Note: It is now legal for us to accept a faxed or e-mailed copy of your dealers license! 
  4. Make sure the dealer knows the firearm is coming from Red Dot Arms. If you used a dealer that we already have on file, call him to let him know that a gun for you is on the way.
  5. We will send you an email when the firearm ships, which will include a tracking number.
