DO I NEED A RAIL ADAPTER, and if so, which one?

The Mantis X line of training systems easily fit the picatinny rail of your pistol, rifle, and shotgun, with the ability to mount backwards and upside down if need be (be sure to let the app know during the set-up screen) dependent upon the needs of your configuration. Should your firearm either not have a rail on which to mount, the rail is already in use, or you're training with a holster that doesn't allow for accessories, we offer a variety of adapters specific to your gun. You can easily search the list of makes and models below to find the right one for you. Should you still not find what you're looking for, then please contact us and a member of our team will be happy to help. 

The adjoining photo shows examples of firearms with and without the proper rails. 

Please verify the adapter product page for compatibility in case the magazine in question is a ten round magazine designed for a firearm available with a standard capacity magazine exceeding ten rounds.
