Sacred Haven of Debauchery

Doesn't a pistol consume fewer action points per shot? I've already forgotten about this, haven't I?

WOKE UP! HELLO! IT TURNS OUT THIS NOOB DOESN'T EVEN KNOW THE ESSENCE OF PISTOLS!
He doesn't know that it's very easy to boost a Gauss pistol to two action points. He doesn't know that you can upgrade a Magnum so that it also consumes only two or three action points per shot. What does he even know? Only how to whine that he has nothing to throw!

But I was using a one-handed weapon, so I had 2.

This doesn't affect the firing rate, but it might affect accuracy or damage. But there are perks that reduce the cost, yes.
