This is a great less lethal optoion for close defence this comes with 30 extra rounds as well as 12 co2 cartridges. In total you get 20 rubber balls 20 pepperballs and 10 rds of powder balls ( which is great for marking the ofender)  These are effective up to 25 feet which is close enough to get the message to the offender be it  a dog or a person. ( not recomended for bears )
