This is my favorite pistol caliber carbine so far. I have shot a full auto MP5, since then i began to look for a pistol caliber gun for home defense and range. It is more accurate and hits harder (longer barrel brings out more velocity) than a 9mm pistol, yet not as loud or flashy like a rifle (you need to consider this especially if you may need to shoot indoors for home defense, etc.). I can hit a 3 in spinner target all day long at 45 yards with only iron sights or a red dot. Also, it uses the mags of my 92A1 so it made an even more ideal home defense equipment. My pistol is in the bedside safe, so if some one breaks in and once I got the pistol and extra mags, I can manage to get the rifle and stick in the mags without struggling to find the right mag for the carbine. I can even take out the mag of my 92 and stick it into the cx4 in emergency, big plus. Almost all operations are ambidextrous, you can even put on 2 charging handle (1 on each side) and that's what I did.
Now a few cons of it (but doesn't stop me from loving it),
1. Stock length. I'm 6'2 with long LOP and I felt the stock is right length for me, and it can be longer if you put on another spacer, doesn't make sense. I wish if it can be shorter so my girlfriend can handle it better.
2. trigger pull. 8.5 lbs not adjustable. Definitely not one of the best trigger I've had, maybe one of the few in the bottom. But it does get the job done, so I don't really care. I'm not gonna shoot it with anything beyond 100 yards anyway. it's a 9mm.
3. buttons position. some buttons are hard to operate without shifting your grip. and like the mag release, you need to have long thumb to reach it. This could also goes to the stock design because it reduced you grip hand movement.
4. felt recoil is not quite much less than an AR. this might because of the blow back design. It doesn't have all those fancy buffer/spring combo like what AR has. So you feel the direct kick other than the muffled and delayed recoil an AR has. This might reduce your follow up shot speed, but it is not as loud as a 223 or making the big flash as a 223, so you get the sight picture quicker.
5. barrel length is 16.25 inch. I wish if they could make it 14.5 and pin a flash hider/compensator on it. Some people clocked a faster bullet speed after they cut it down to 14.5 comparing to the factory setup. And if you look at its military counterpart - MX4, its even shorter than 14.5 inchs.
6. side and bottom rails. You need to buy the whole set of other side rail to hang the bottom rail for a foregrip, and all these are plastic, well, polymer if you insist. So it can get loose over use, and you cannot adjust it (the bottom rail). Also, if you want to get Aluminum side rails (and Beretta do sell them), you are wasting the 2 plastic side rails because they don't have a metal side/bottom rail set for sale.
However, these are all no reason for me to refuse this gun, especially at it's price. Those sig MPXs are sold for 2k and above. Also, cx4 is very easy to disassemble and clean.
