Better aim low, really low for the first round, after that muzzle climb will give you, maybe to hits. The rest, who knows. I suspect the pistol has a full auto cutoff.
The military had to limit the AR-15 to three round bursts because of troops just pulling the trigger and hoping. Does not work so well in a fire fight.

I've seen youtube clips of Glocks running full auto both with and without detachable shoulder stocks (SBR?). They do not appear to be that hard to hold on target even w/o the stock. I saw one clip with a guy firing two at once and keeping them both straight and level. But like all full auto pistols, they don't seem to fill a need except to burn up excess ammo.
