This drill is simple but will go a long way in diagnosing trigger pull. All you need to do is ensure your firearm is completely unloaded, place a penny on top of your front sight, point the weapon in a safe direction, and then slowly pull the trigger. If you can do this without the penny falling off the gun, we know you can pull the trigger without interrupting weapon alignment. Clearly, if you cannot do this without the penny falling off, you should work more on your trigger pull.
