I am active duty military. Mags aren't really considered much of an issue. It is hard to train without loosing some. The pawnshops are full of them and a lot of units have the soldiers store them at home. They are generally treated like TA-50 (your rucksack etc). In fact pre ban they were treated like an expendable item and where just given away like almost like office supplies. Since the ban the prices went way up and now there is generally some accountability required and sometimes soldiers will have to pay for them if they loose them and cannot find one somewhere. Pistol magazines are a little tighter but I think they cost more. No one stole these I can't even tell you where most of the ones I have had came from. They are like that extra canteen or web belt just something picked up over the years. Even those I saw in the drawers this weekend, were the personal property of coworkers. This unit does not have soldiers keep thier magazine between ranges since we work in an office. The question was not about acquiring them I know I can do that, also I can own them, just like I own some of my other gear. The question is, Are the marked ones legal to use in my civilian weapon?
