What I'm talking about is the 'LEO exclusion' for 922. Guys, LEOs can have a LEO-only gun ONLY if they can get their boss (CLEO) to give them a letter to get one. They cannot just go out and buy them whenever they want one. Most departments WILL NOT give out these letters due to liability issues, or will specify the particular weapon to be purchased. Further, Even if a LEO buys the weapon, if he leaves law enforcement for any reason (or even goes to another department where the weapon is not authorized), he must turn it in. If he doesn't, he is comitting a felony.
As to magazines, again, a letter is required. Further, when the LEO turns in the weapon/magazine, he IS NOT COMPENSATED. He just made a donation to the department. ATF HAS charged a few officers regarding this stuff (more LEOs than citizens with 922 violations).
Not looking to start anything, just everyone please understand that LEOs don't just 'get to have' anything they want. When I left my former agency, I was actually contacted to make sure I had turned my stuff in. Luckily, I turned in my two mags and AR lower to an FFL holder (LEO supplier) the same day I quit, so I was in compliance. If you ain't a CLEO, no free rides.
