Why the DB15 Midnight Bronze Wins
Having run this pistol through drills at our Spring, TX 100-yard range, the DB15’s 7-inch barrel delivers surprising accuracy for its size. The Midnight Bronze Cerakote isn’t just for looks – it’s a durable finish that resists wear better than standard anodizing. The M-LOK handguard gives you real estate for lights or grips without adding bulk.
