Detailed Features 

The gas-operated action handles 2¾" and 3" loads without adjustment. The TruGlo fiber optic front sight improves target acquisition in varied lighting. The Inflex Technology recoil pad redirects the stock path away from the shooter's face during recoil, reducing felt kick over extended sessions. The back-bored vent rib barrel is designed to reduce pellet deformation and tighten patterns. Three Invector Plus chokes are included (Full, Modified, Improved Cylinder). Controls are mirrored for left-handed use. The safety, bolt release, and ejection port are all set up for left-hand operation. 
 

Usage 

Left-handed shooters rarely have many purpose-built semi-auto options at this price point. The SX4 Lefty addresses that directly without requiring any modification. At 7 lbs with a 28-inch barrel it handles well for upland birds and clay targets.

Left-handed shooters looking at the SX4 Lefty mostly comment on the fact that it exists and works well. The reversed controls are properly implemented rather than an afterthought, and the gas action earns its usual reputation for smooth cycling.

Recoil management is consistently noted as a positive, which is a real advantage for anyone running a high round count at the range or in the field.

The critical feedback mirrors the standard SX4 pattern: some owners note a break-in period before the action runs at its smoothest, weight at 7 lbs is heavier than some alternatives, and the price sits higher than comparable semi-autos in the market. Matte finish durability comes up occasionally, with a few owners noting it shows wear faster than expected under hard use.
