I have the APX Carry, not the A1.
It is a perfectly adequate gun. I have no strong feelings for or against it. I admittedly haven't shot it in years, but I do remember mine shot several inches low. I also remember one or two malfunctions in the few hundred rounds I've had through it, but that was cheap range blasting ammo.
If you look at pictures of the old Beretta Nano and the APX Carry side by side, you can clearly tell that's its lineage, not the APX full size.
The magazine capacity is obsolescent in the now crowded market of "micro-9s" which hold a minimum of 10 flush, but you can still make it work. This is likely the main reason why they are being offloaded at a markdown.
