I currently own one Luger, a 1920 commercial, which is about the most dirt-common Luger you can own. I have in the past owned a Mitchell 6" (which I had a LOT of trouble with) and a mismatched 9mm with a very dark bore which shot well and which I wish I had kept. They are really cool guns that will do pretty much nothing but go UP in price. If you do get a .30 cal you will either spend a lot for ammo or have to start reloading.
