Verified clear. Twenty strong-hand-only presses on the squares. Put your support hand flat on your chest and keep it there. Grip harder than you think you need to and press straight back.
Twenty rounds at 5 yards, strong hand only, four rounds per square. Every hit goes inside its square.
Your support hand is often busy with a light, a radio, or a door. This is the common case.
Your other hand may be holding a child, a phone, or a door. Shoot it the way it will happen.
Carbine version: shoot from the strong shoulder with the support hand off the rifle, at 15 yards.
AUX (when ready): all twenty inside the squares, strong hand only.
One hand is the likely case, so it should not be the neglected one.
Without two hands you cannot muscle the gun. Press cleanly instead.
Notice where the gun moves during the press with one hand, then fix the grip.
The other hand has someone in it. This is your drill.
Compare this with your support-hand score from Oct 16 and work the weaker side.
Layer: draw one-handed for the last five reps, dry.
Dry-fire: no ammunition in the room. Verify the firearm is clear — twice. Use a safe backstop. When you finish, say it out loud: “Dry fire is over.”
Non-negotiable. Every drill, every rep, every time. This applies to live fire and dry fire.
