The SIG Sauer M17 P320 ASP is a realistic CO2-powered air pistol that replicates the U.S. Army’s official sidearm. Featuring a rifled steel barrel, full blowback action, and belt-fed 20-round magazine, this pellet gun delivers authentic shooting performance in a durable, metal and polymer build. It’s ideal for target shooting, training, or just backyard fun.

Why choose this pistol?

• Realistic Design: Faithful to the U.S. Army-issue P320 M17 with full blowback action and authentic dimensions.
• Rifled Steel Barrel: Delivers improved accuracy and tighter grouping with .177 caliber pellets.
• 20-Round Belt-Fed Magazine: Allows for extended shooting without frequent reloads.
• CO2 Powered: Uses standard 12g CO2 cartridges for consistent power and easy refills.
• Solid Build: Metal and polymer construction provides a realistic weight and feel.

Why not?

• Double Action Only: Limits precision control compared to single or dual-action triggers.
• Plastic Components: Some external parts are polymer, which may not appeal to full-metal enthusiasts.
• CO2 Not Included: Requires separate purchase of 12g CO2 cartridges to operate.

Pro Tip: Use high-quality .177 caliber pellets and keep extra CO2 cartridges and magazines on hand to extend your shooting sessions without interruption. The blowback adds realism—but also uses more CO2—so plan accordingly.
