Are there any officers out there working for departments that have been issued the Karbon Arms MPID? Our department had purchased the Stinger Systems MPID and had great success with it. When Stinger got bought out by Karbon they replaced our Stingers with the Karbon MPID. We have had a lot of problems with this product and I was wondering if any other officers out there have had the same experience. Wanna kill these ads? We can help!
