Registering my handgun on post?

On most Army reservations, the Provost Marshall is located at the same place that you get your DoD decals. There shouldn't be much more information required than what you already have: Name. Address, Felonies or not. Etc. The only kicker is is when you register that weapon with the Provost Marshall, that Privately Owned Weapon now needs to be stored in the company arms room, forever and ever amen. Until you move off post of course...
