IRP Association, LLC has obtained the patent rights to a 12 gauge defense round for law enforcement known as "Polyshok IRP". They will reintroduce the round formerly know as Polyshok into the law enforcement and home defense ammunition market as... Maxstop IRP.
The Maxstop IRP (Impact Reactive Projectile) is not large, but it hits with so much punch that it’s been described as a type of shaped charge. Because it is a powdered lead projectile, the IRP is a good option when the shooter has concerns about over penetration in close quarters situations.
IRP Association LLC wants to make IRP the first choice in shotgun ammunition for Police Officers and personal defense consumers. When faced with extreme shooting situations, IRP will protect those who rely on the round’s superior performance.
