I apologize for the delay in responding, and thank you for posting. Safety comes first with any prop weapon, even airsoft. Look for a prop house or a local armorer who rents replica or non-firing guns and can supervise on set. Always notify local police before filming with realistic-looking weapons in public, keep replicas covered between takes, and never point any prop at a person unless the armorer has cleared it. Many productions now add muzzle flashes in post, which is safer than blanks. I hope the action movie turned out great.
