45 is a big boy round but can be controlled. If you haven't, try the 70-30 grip out. By that, I mean 70% of your grip should come from the support hand and 30% from your trigger hand. Too much squeeze from your trigger hand will cause the gun to wobble. Plus, pulling the trigger with a controlled squeeze will give you more control. I didnt watch to see if you did, but a lot of people slap the trigger and throw their shots low.
