Tanfoglio Defiant Stock I 10mm 4.5" Barrel 13+1 Black Steel

The Tanfoglio Defiant Stock I delivers 10mm Auto power in a precision-engineered platform built for serious applications. This full-size pistol combines Italian craftsmanship with practical features that competitive shooters and law enforcement professionals demand.

What Makes This Different

The Defiant Stock I stands apart with its all-steel construction and integrated Picatinny rail system. While polymer-framed competitors sacrifice durability for weight savings, this pistol maintains structural integrity under sustained high-pressure 10mm loads. The serrated slide provides positive manipulation even with wet hands, and the beavertail frame design eliminates slide bite during rapid fire sequences.

Key Features

• 10mm Auto chambering delivers 650+ ft-lbs energy with premium loads
• 4.50-inch barrel optimizes velocity while maintaining compact profile
• 13+1 capacity provides substantial firepower in standard magazine
• Picatinny rail accepts tactical lights and laser accessories
• All-steel frame and slide construction rated for +P ammunition
• Wood grip panels offer traditional aesthetics with secure texture
• Serrated slide surfaces enable reliable operation in adverse conditions

Field testing demonstrates consistent 2.5-inch groups at 25 yards with quality ammunition. The 10mm chambering excels in hunting applications where barrier penetration matters, while the rail system accommodates duty accessories. Weather sealing protects internal components from moisture and debris during extended outdoor use.
