Pistol Grip SAP6

[aiwa]

I'm trying to expand my inventory of restricted pistol-grip shotguns. I've been preoccupied with DA & Dlask, but I saw a pic of a SAP6 the other day with the shoulder stock detached and sitting next to the pistol grip, which remained on the gun. How easy is it to do this? Is it just a matter of pushing that pushpin and removing the shoulder stock?

Removing the stock takes 5 seconds, 3 on a good day.

Is it really just that pushpin looking thing on the pistol grip?
