I have no actual experience using them, other than playing with them at an in store display.
What I can tell you is this: I don't care for them, but I've read about tons of people that absolutely love them. From what I've read they aren't as precise, but allow for the shooter to be much quicker on target along with quicker follow up shots.
IIRC, they do have them on display at Sportsmans. I know they used to have them on display at Keith's. Check em out, if they seem like they'd work for you give em a shot
