Will a beretta px4 sub compact accept a beretta 92 magazine?

Most gun dealers will tell you yes, as I have discovered that the majority of them are under the false impression that beretta 92 series mags fit the storm series guns. They do fit and lock in place, however they don't feed properly. The storm series mags are interchangeable between the Cx4 rifle and the Px4 pistols, so long as they are the proper caliber. Just because something fits doesn't mean it's right.....after all, why would beretta make specific mags for the Px4 if the existing mags from the 92 would do the job? Don't be fooled by a dealer who sticks a 92 mag in your gun and says "see? it fits!"
