Red Dot help....

Hey guys.......I finally got my pistol back from being fixed/tuned. I tried the red dot a little while then the UTG scope out of my junk drawer, then back and forth. Took me a while but I figured out the red dot was not for me. Took it back to Walmart and got a refund.
Looks like I'll be sticking with scopes from now on ;-) I'm not even sure this pistol is the one for me at the moment? Looks like I'll be sticking with pups instead! LOL
Maybe it will group better once I get my stock attached to the pistol grip? The accuracy of my pups and air rifles have spoiled me. Maybe I expect too much out of this pistol?
Bumfuzzled for now ;-)
