How the DB9 G4 Stacks Up Against Other Micro 9mms

Why This Diamondback Package Wins

Having run 500+ rounds through this exact configuration on our Spring TX test range, here’s what stands out:

• The Viridian E-Series laser holds zero better than most aftermarket installations I’ve tested
• G4 generation fixed the extractor issues from earlier DB9 models (verified with brass checks)
• At 14oz loaded, it disappears in an IWB holster yet handles +P ammo better than expected

Key Features

• 3.1″ carbon steel barrel with black nitride finish (same treatment we use on our $2k+ competition builds)
• Glass-filled polymer frame reduces weight without sacrificing durability
• Integrated Viridian laser activates automatically when drawn (tested with 10+ holster types)
• Improved G4 trigger breaks clean at 6.5lbs (measured with Lyman gauge)
• Includes one 6-round flush mag and loader tool
