How the Diamondback DB9 Stacks Up Against Competitors
When you’re looking for a compact 9mm, you’ve got options. Here’s how the DB9 compares to two popular alternatives:
| Feature | Diamondback DB9 | Taurus G2C | Ruger LC9s |
|---|---|---|---|
| Material | Stainless steel slide, polymer frame | Polymer frame, steel slide | Aluminum alloy frame, steel slide |
| Finish | Muddy Girl Camo Cerakote | Blued | Blued or stainless |
| Capacity | 6+1 | 12+1 | 7+1 |

| Weight | 11 oz | 22 oz | 17.2 oz |
| Price | $219.99 | $249.99 | $329.99 |
Why the Diamondback DB9 Wins
Having tested dozens of compact 9mms on our Spring, TX range, the DB9 stands out for three reasons:
- Ultra-lightweight at just 11 oz – you’ll forget it’s in your waistband
- Unique Muddy Girl Camo finish that holds up better than cerakote on most budget pistols
- True single-stack slimness – 0.88″ width disappears under a t-shirt
Key Features
- 3″ barrel balances concealment with shootability
- Stainless steel slide resists corrosion
- Glass-filled nylon frame reduces weight
- Fixed sights (drift-adjustable rear)
- DAO trigger with 6.5 lb pull weight
- Manual safety and magazine disconnect

Who Should Buy This
Buy it if:

Frequently Asked Questions
Is the Diamondback DB9 reliable?
In our testing with 500+ rounds of mixed ammunition, we experienced 3 failures in the first 50 rounds (break-in period) then flawless function with 115gr FMJ. +P ammunition isn’t recommended.
What holsters fit the DB9?
It fits most holsters designed for the Ruger LC9s. We recommend checking our holster selection for options.
Does the camo finish wear off?
Cerakote is more durable than paint but will show holster wear over time. The stainless steel underneath won’t rust if the finish wears.
Where can I buy the Diamondback DB9 online?

Is there a warranty?
Diamondback offers a 1-year limited warranty. We handle all warranty claims for our customers.
How does it compare to a Glock 43?
The Glock 43 is 4 oz heavier with slightly better ergonomics but costs $150+ more. Both are reliable – choose based on budget and preferred grip angle.
Can left-handed shooters use it?
The manual safety is right-side only. Magazine release is reversible.
