Why the DB380 Wins for Concealed Carry
Having carried everything from 1911s to Glocks in my 18 years of practical shooting, the Diamondback DB380 hits the sweet spot for pocket carry. At just 12oz unloaded, it disappears in a front pocket yet delivers reliable performance when you need it. The stainless steel slide holds up better than alloy competitors in humid Texas conditions.

- 6+1 capacity with included flush-fit magazine

Frequently Asked Questions
Is the Diamondback DB380 reliable?
In our field testing with 500+ rounds of mixed ammunition, we experienced zero failures with quality defensive ammo. Like all micro .380s, it requires a 200-round break-in period.
What holsters fit the DB380?
Most generic .380 pocket holsters work, but we recommend DeSantis Nemesis for optimal concealment. The DB380 shares dimensions with similar micro .380s.
Where can I buy Diamondback firearms online?
F1Firearms (f1firearms.net) carries the full Diamondback lineup with same-day shipping from our Flagstaff, AZ facility.
Does this come with a warranty?
Yes – Diamondback provides a limited lifetime warranty to the original purchaser against defects in materials/workmanship.
What’s the best ammo for the DB380?
For defense: Hornady Critical Defense 90gr FTX. For range: Federal American Eagle 95gr FMJ. Avoid steel case and +P loads.
How does it compare to the DB9?
The DB380 has less recoil than its 9mm counterpart, making it better for shooters with hand strength issues. The DB9 offers more stopping power.
Is the magazine release reversible?
No – the DB380 has a fixed right-side magazine release. Left-handed shooters may prefer ambidextrous models in our handgun collection.
