Shopper is there a power reducer switch?
FRANK O There is a high/low power selector switch just above the handle on the left side of the gun.
I personally do not use it as my gun is always used at full power.
UJEANIA L No. The only action besides the firing trigger is a safety catch that flips up and down to save those unentended firings.
ALAN M R Not really. You could bleed some air out of the gun - but I wouldn't.
It's a pain to put back. The gun works great as is. I still use mine all the time.
DAN R Thumb switch on the left side. Hi and low setting so you don't destroy your tip on rocks
