It's more like a Russian version of .22TCM, slightly smaller because the basic assault rifle cartridge is slightly smaller.
In terms of comparison it acts like a .25ACP with armor piercing ability and about twice the penetration in flesh. In other words its superior to 9mm. In fact all of the guns that use it have a simple modification to .25ACP and are exported as such Not that .25ACP or 9mm are bad, I'm just saying this particular cartridge is superior.
Pic related is a gun that uses it which carries 24 cartridges, compared to similar size Glock 17 which has only 17, in other words 30% more bullets per gun. That means carrying 1+1 mags, instead of 1+2.
Police requirements for a cartridge are ability to penetrate door and windshield of a car, which this meets. FBI requirements are 11 inches in flesh, which this exceeds. It makes a hole roughly the same size as any other pistol cartridge, so it's just as lethal. FBI also complained about kick from .45 and 10mm, they claimed lower rate of follow up shots. The only requirement 5.45x18 fails is overpenetration. But that's a gay requirement anyway, an officer should pay attention what he's shooting at. It meets all the relevant requirements while providing more capacity and less kick, it's superior.
I'm not seeing how it would be negative. Maybe some small dimensions can be re-worked to make it more useful in the west, but it's pretty damn good.

I'm not bragging just explaining why the toy was damaged. And I seriously doubt America has no one that buys from BD, considering its a US based company and didn't even export at first.
