The UNIT9 runs blanks, non-marking rounds and marking rounds. Change the ammo and you change the drill. 

• Blank Ammo: 8g threaded CO2 cylinders only. No projectile. Each cylinder cycles the slide so you can run draws, presses, reloads and malfunction clears with real recoil, anywhere you can train safely.
  
• Non-Marking Ammo:  8mm projectiles that leave no residue. Useful for marksmanship and target work where you want hits on paper and no cleanup on the walls, floor or gear. Most resilient round for outdoor use.
  
• Marking Ammo: Every hit leaves a visible mark. Use them in scenario and force-on-force training where you need to see who got hit and where. Comes in four colors so each team or shooter can have their own.
  

All marking and non-marking rounds are 100% biodegradable, lead-free, brass-free, and do not contain primer.
