15 strong-hand-only presses, 15 support-hand-only, slight inward cant. Build the one-hand grip from scratch — it is not half of your two-hand grip.
5 yd: 10 rds strong-hand, 10 rds support-hand, 10 rds freestyle to finish clean. All inside the scoring rings.
Heavier gun is steadier one-handed but punishes a soft wrist. Lock it.
Light gun + one hand = honest trigger feedback. Listen.
Improvised support-side mount, 15 yd max, slow. Awkward is the curriculum.
AUX (when ready): support-hand group inside 6 inches at 5 yd.
Refuse the highlight reel: judge sessions by the median rep, not the best one.
You won't like being this slow. Be slow correctly.
Your eyes don't care which hand holds the gun. Same visual standard.
The day this matters, your other arm is doing something more important. Train it now.
Track the strong/support delta — it's a number, and numbers shrink with reps.
Layer: one-hand from the ready position, not pre-mounted.
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.
