I guess the question now is... what's what?
What I mean is if I have it in the closet, and I have a sudden need to grab it and fire as is (stock fully retracted) I can do so from the chest, sighting inline with the barrel, but a couple inches above.
From the shoulder, proper shooting position, the factory stock never felt right. The comfort statement refers to that, the Knoxx feels much better while fully extended in a proper sport shooting stance.
In an HD situation, short LOP planted in the chest is handier, quicker to deploy, and within 7 yards, easily accurate enough. (for me, that is...)
