I'm not sure...
The PDW or CPW or whatever is always a bit of a white
elephant.
Not many armies have the money to equip their clerks and storemen
with expensive little new toys that also use a different
calibres.
Most armies just give their non-combatants old ARs. They don't even
get carbines as thse are usually reserved for special combat
troops.
The simple logic being that since a clerk's job is to type, the
money should be used to buy him a laptop, not a expensive little
weapon that he's not gonna use anyway.
The SAF, for example, bought FN P90 - a PDW - for SOF.
And the PPSh is actually frontline issue. Some entire battalions
are armed with nothing but PPsh.
there's nothing wrong with mag-in-grip layout. The famous Uzi is
just such a weapon. it all depends on the individual weapon's
overall design.
My problem with most SMG or PDW or CPW is that, they are almost
as bulky as a carbine, though shorter. Nut they fire a short range
round that is also less lethal. And even for clerks and cooks, if
the HQ is attacked by enemy, I would prefer a carbine to such a
small calibre weapon.
For army officers of a very senior rank un the field, would you
want to have such a heavy load strapped to you at all times? Better
to stick to pistol with a carbine on standby.
In military this looks more suitable for certain kinds of special
ops.
...
For normal police patrol, this is overkill. The PC will get body
ache with this thing strapped to the leg for whole day.
Maybe for show of force like installation patrols, Reserve Units
and SWAT etc.
