After a couple of hundred rounds you are wasting your time and your ammo. Unless you are in a 3 day match there is no need for endurance training with a pistol. Use the extra time to lift weights, dig up the garden,. go for a walk, play a little basketball. Physical conditioning will help you more than trying to keep tired glazed eyes on the front sight. Then when you really need to shoot you will have the stamina to do it.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
