Breathing, grip, sight picture, squeeze don’t jerk.
Breathing- don’t hold your breath. Take a breath, start letting it out and start squeezing the trigger at the same time.
Sight picture- line up your sights the exact same way every time. Focus on the front sight, the target should be a little out of focus. And start with a bullseye target at 5 yards. Three inch groups are the goal. Once you’re consistent at 5 yards, move it back to 10 yards. And so on, in 5 yard increments, out to 25 yards. Start off using iron sights, you can switch to the optic of your choice once you’ve got the fundamentals in place.
Grip- take your time setting your grip. If your grip is different from shot to shot, that affects your group. After a while, you’ll be able to feel it in your hand when your grip is right.
Squeeze the trigger. Unconsciously jerking it and/or anticipating the shot is going to put your shots all over the place. The shot should be a surprise, because you’re concentrating on the sight picture and keeping your breathing steady.
Start off using target ammo. Once you get to where you can consistently put 3 inch groups on paper at 25 yards, then you can start practicing occasionally with EDC ammo. Same goes for learning your draw from holster. Right now you want to instill the right muscle memory for grip, breathing, sighting, and trigger management. Take your time, you’re working on precision. Speed comes later.
