Analysis

This variant applied the Gen4 ergonomic and recoil-management updates to the subcompact .40 S&W platform, delivering the cartridge's power in a highly concealable package often selected for backup or deep-concealment carry. The dual-spring setup was intended to moderate the recoil impulse in the compact frame and lighter slide while supporting reliable function across various .40 S&W loads. The model served as a common law enforcement backup weapon and civilian defensive option, with many units reaching the secondary market through agency trade-ins as departments moved away from the caliber.

Equip this pistol with a finger extension and it becomes an 11+ 1 or a 13+ 1 without increasing the size beyond what one can carry in the front pocket of a pair of cargo pants or a pair of loose fitting jeans.
