The CX4 is adaptable to accept any full-size Beretta PX4, 90-series and 8000 series magazines (using optional adapters), thereby saving existing Beretta users the expense of additional magazines.

They make 2 models - PX4 mag model, and 90 Series model.
I don't know what the "8000 series" is.

Also, look at the Keltec Sub2000 if you have any Glock handguns
