Other than Tokarev's not really, and even those I got from different countries because they're cheap and they work and I love the calibre. I have two Glock 17's,,but they're different generations. If you really love the platform its never a bad idea to have two of the same gun,,,Im not into modifying but if you are,, you can keep one stock. Also, if you compete with one or use one in the field a lot and it gets abused, its good to keep a safe queen as a backup, or to start using if you retire the other one.
