I don't have either so I may be making this up, but its the internet so I'll give it a shot. They may be interchangeable with a slight modification to the mag. There are several firearms that use the same size mag body. The only real difference is the notch for the mag release. Beretta 92/sig 226/s&w 59/walther p99 and others, the sw9ve may be one of them. A new notch can be very carefully cut to make them function in different guns. It needs to be pretty precise, it doesn't take much to overcut it. I've used Beretta mags sucessfully in my sig.
If Hoppy is correct and the angle is also different then disregard everything I said.
