I just ordered the "Beretta" model in .40 hoping to add the SIG mag catch and convert to use my .40 CZ 75b magazines.
I will take some photos once I have the rifle and magazines in hand. I did verify that the mags for the .40 fit properly in my 9mm CZ - if the Beretta 92 mags fit in the Beretta 96 mag well and the 9mm and .40 SIG pistols catch when swapped, then I suspect the CZ mags will interchange as well.
Here's knocking on wood!
How did this work out for you?
