Love mine too, the magazine in PX4 won't feed steel case ammo. It has trouble "organizing" it and jams up inside of the clip. I read it in a forum somewhere, didn't believe it, bought some, now i believe it. Never a FTF or FTE with brass.
Trouble organizing? Does the magazine gets confused? Lol Well I hear it eats up any ammo you fed it. Will see FTF's do happen but the majority of the time it's do to user error and or an unmaintained firearm. Thanks for the heads up though.
CONGRATS on your/her New PX4-SC! When I first bought mine, I also purchased the Snap-Grip Mags, so I could get a better grip on the pistol. It worked just fine, however, Beretta recently came out with a Mag Adapter for the 17-Round Mags, that fit the PX4/CX4 Full Size/Carbine Mags that I have. I had three extra 17-Round Mags, and added the Adapter to them. Now it gives the Grip that Full Size feel, and it's great! The Adapter fills in the gap between the bottom of the Grip, and the bottom of the Mag, so it's now just like a Full Size Grip.
