You forget that you have to charge the weapon. And that takes two hands when you first put the first mag in. And you have to hit the release to charge it when to slam the bolt forward. Now, tell me again exactly how it's done, step by step. And please specify the exact model number of the gun so I can research it fully. You don't mind if I don't take just your word for it.
I've seen enough. NO it operates fine for a single hand on mag change. It's light and uses some steel pieces which is a huge plus. It's light. All in all, as a plinker it's going to be a fun gun. That being said, it's short, real short. At 50 yds, it's not accurate at all. It lacks power. The 9mm just doesn't make it. I don't see it being used for varmints. And you are better off with a 9mm handgun for home defense. While they tried to make it like an AR, it failed miserably. It's a toy. Better to buy a 9mm handgun and a decent varmint rifle than this one unless you just want to spend a lot of ammo shooting at beer cans at short range.
It's a Beretta CX4 Storm, operation is identical to an AR, and I'm not understanding how it "takes two hands". There aren't any magazine fed rifles or pistols that only take one, unless perhaps you straps some weird mag-holder to your leg and poke the weapon down on it lol.
In any event you haven't answered the question, and you've added yet another element - ammo. So is it the history, the features, the ammo, or all of the above?
I already covered this. It's a toy. It's a cross between a 9mm handgun and a daisy red rider. It lacks power and accuracy so that alone disqualifies it. Now, build the same weapon just a bit bigger, better quality and a more lethal caliber and it might qualify. But as it stands, it's just another plinker.
It’s basically a semi auto machine pistol. So if caliber, distance, and stopping power are the issue, then smgs are fine?
You brought up ONE weapon. You need to stick with that instead of trolling for generalizations. I gave a pretty accurate description of your one weapon after viewing one world class shooter operate it on a mixed range. Yes, he had a ball but he also missed a bunch due to a lot of factors. It might be extremely lethal if it were a full auto but as a semi auto with limited ammo, it's a plinker. It is too large to replace a handgun so it even fails there. You have to fill ALL of the features of the AR to be considered the equal of the AR because the AR fills ALL of the criteria that Stoner required it to fill. And nothing on the market today does a better job.
I didn’t bring it up. So a semi-auto SMG should be perfectly legal, like these...

I can just use Colorado Firearms Regs on this one.
9mms. The problem here is, these aren't any more powerful and more cumbersome than a Handgun. And they are actually less accurate if you are rushed. I can site shoot faster and I can spot shoot faster with a handgun than I can with any of the following. They may be legal but they really aren't good choices. I put them into the plinker category.
MP-5 legal with the proper mag
UMP-45 legal with the legal mag
PM-9 Legal if you remove the capability to use the forward pistol grip and use the proper mag and remove the ability to use a silencer. The problem is, removing the forward pistol grip throws the balance completely off.
28 or more Grains of Powder per Round. These two are designed to go out and reach out. They are both designed for crew weapons where you sometimes have to dismount and fire on targets further than 40 yds away. You may have to go to 50 or more yds.
MP-7 This is class as a pistol. It's round is a 4.6 X 30 which has enough power to penetrate many types of body armor. The rounds are fast, real fast and small. While not quite in the same class as the 556 nato, it's pretty danged close for such a small package. But due to the available equipment and mags, it's considered illegal in many States, not all. What keeps this out of the mass shooters hands is the cost. It's expensive, really expensive.
P-90 Not Legal as the P-90 since the P-90 is a full auto. But the PS-90 is the same gun in a Semi Auto. But you can't remove most of the features on it because they are built into the frame. It uses a 5.7X28mm which is just below the 556 Nato Round. It's slightly larger, slight slower but still has enough punch to do the job. The problem this one has is, it contains a huge amount of ammo. It's mag is a 50 round mag. Luckily, this puppy (see the pun?) is so expensive that the mass shooters will overlook it.
PPM90M1 Not legal. Exceeds Max Ammo with it's 64 round mag, Designed for close quarters only. The smallest mag is 32 rounds and it still exceeds the 15 round max by a large margin. This thing is designed for house to house fighting, not for home defense. And it's only found in Russia in their Military and, of course, Video Games. Good luck in getting one. Oh, it's like anything else, if you really, really want one and have enough money you can get one. But remember, it's a full auto, limited export item from Russia.
So I found only two of your guns that could do the job of the AR if there are no local laws against having them. But you had better have really deep pockets. So, what is your point on this one again?
