Here's my opinion on the Move with sharpshooter gun, fwiw, since it seems a lot of people want opinions on this set up.
I have a decent background in FPS games, was very good at COD games with a controller. Using the sharpshooter for these games definitely takes some time to get used to. It's almost as if your brain forgets that you are aiming with the gun in your hand. For me, especially, it was a little tough because I move and shoot at the same time in FPS, so aiming the gun while moving the joystick can be a little weird. But I've never had problems calibrating the gun and I've never had problems losing calibration. I've played for several hours straight on multiple occassions and never had to stop to recalibrate. I don't know if people aren't doing it right/aren't playing with enough space, but I personally have never had any problems like that.
The accuracy of the gun is ridiculous. After a certain while of getting used to the gun, I thought to myself "I'm going to try for headshots." You aim across the map and go for headshots, you get the headshots. I remember someone saying the gun is not accurate, especially across the map, and I just haven't experienced this. Using the gun is insanely fun. There can be a large period of time where you have to get used to it, but if you enjoy using a real gun at those arcade shooter games (and who doesn't?) then I think eventually you will like this.
