I remember Zen.....attained Zen in the late 80's. It means becoming so proficient with your firearm that things just flow...... .70 draws on target, sub 4 second El Pres, being able to hit pop cans in the air, shooting clays going away from you with a .45, one second reloads, making shots that surprise even you.......it's muscle memory......2nd nature..... Hope I can get it back!
