I have about 12 of these Mauser Parabellums-all different. I have not shot them and from what I've seen the grips get loose if you shoot them much. Regardless of what you choose, it won't hurt to look at Gun Broker, I search "Mauser Luger" and a couple hundred, including Mauser Parabellums, show up. If you are patient you can get a good buy, below is a nice early 9mm 4". Good luck, Joe
