Hell no. Here in America, due to some law that forbids purchase of full-auto firearms developed past a certain year (in the 1990s I believe), all full-auto weapons cost multiple thousands of dollars.
In addition to that, I need both a federal licence and local approval to own any full-auto weapon. I would have to have a separate licence for each full-auto weapon I would own. So far that amounts to about 2, and the process takes a few years generally. Maybe my Italian descent can help me here
Ammo is no problem, as it fires a standard 9mm cartridge, which I personally reload, and can get them for around 10 bucks for 30 rounds. I also intednd to eventually get one of these, along with a Sturmgewehr44 (the A295, used by a few Rebel forces) and a 'broomhandle' Mauser C96 (Han Solo's Dl-44). So far, the Mauser looks like the first of them, as it is far cheaper, and much easier to get (one rather cheap local licence that takes about a month to get at most).
