Introduced in 2017, the Defiant Stock I is the first model featuring FT-Italia's new design language. Featuring new slide checkering and frame design, this pistol is set up specifically for Practical Shooting Production Division and well as IDPA SSP and ESP Classes. This model allows the new shooter to approach the world of competitive shooting sports and the seasoned shooter to compete in divisions that have been until now reserved for very few models. The Stock I uses a traditionally rifled cylindrical barrel that provides excellent results with all types of ammunition. The frame of the Stock I is similar to that of the Stock III and has a full length railed dust cover to aide in better balancing of the pistol.
