Tomorrow, I will be heading to Applied Ballistics to test out my Ruger 22/45 Threaded Barrel. It does not have iron sights, only a top rail. I've installed a Primary Arms Micro Dot on it. From just playing around with the gun in my room, I've realized it's going to a lot more difficult to shoot than initially expected. I'm having a hard time keeping the dot still in my line of sight. Every slight head move, or movement of the gun, seems to make the red dot dance all over the place. If you couldn't already tell, I've never shot a handgun before that wasn't straight iron sights. Are there any tips or tricks to keep everything consistent? 
Any input will be greatly appreciated!
