These floor plates are used to easily identify training magazines. The orange plates are particularly helpful when practicing malfunction drills, as you can load these magazines with a mix of live and training / dummy rounds before a trip to the range (and forget the load order to make the most of training!). The blue plates are most often used with Simunition or other non-lethal training ammunition.

These will fit Glock OEM magazines in 9mm, .40, .357, and .45GAP (including models G17, G19, G22, G23, G24, G26, G27, G31, G32, G33, G34, G35, G37, G38, G39).
