Why the DB9FS Wins
Having run 500 rounds through this pistol on our 100-yard range in Spring, TX, I’ll tell you straight – the Diamondback DB9FS outperforms its price point. The aggressive grip texture stays locked in your hand during rapid fire, and the 4.75″ barrel gives you better accuracy than most compact 9mms. For under $200, you’re getting a pistol that shoots like models costing $100 more.
