Beretta mags in a Wather P99 ? ? ?

[Xak]

In the "laws" section someone mentioned that P99 preban magazines are hard to find, but there are plenty of Beretta prebans that can easily be modified to fit the P99 (9mm).

Anyone know how to do it? Are they reliable?

Anytime you modify something like that, reliability will take a hit.
