I recently got a detroit marked glock 22 and it appears to have two preban mags with it. I have looked at the pics on this forum and they look like the examples of preban's that I have seen here. They have DPD on them, but not LE ONLY. I am new to glocks so and preban mags so I don't know if a mag that is marked DPD would be considered preban? Any info would be appreciated.
