Have no idea? The one I have is great shape, with all the accessories. I don't think is a very powerful cartridge. I don't think I would want to get hit with it tho!
A friend told me that they are close to thousand dollars now. Don't know if that is true or not. The one I have is in fantastic shape with all the accessories.
I had my life time permit before the carry law that is effect. If I would travel to another state and was asked to see my permit, I would at least have it for the rec-cpical agreement...
