Firing stance is NOT a fundamental. Let me say it again so you'll know I said it on purpose:
Firing stance is NOT a fundamental. Why not? If you can hit with Isosceles, and I can hit with Weaver, than neither stance is a requirement for good shooting. Right? Therefore NOT a fundamental.
So, what ARE the fundamentals (with a nod to Brian Enos)?
- She must find the target. A clear target focus will help her quickly drive the gun onto the target.
- She must put the gun on the target. Maybe literally touching the target, but usually visually putting the front sight on the target.
- She must keep the gun on the target while she fires the shot. When she sees the muzzle flash, she will know the bullet has left the barrel.
So, teach her how to use her eyes to find and focus on the target.
Teach her to put the gun on the target using whatever stance feels most comfortable. They ain't called hand-s-guns! She can shoot one handed all day long and still hit the target with no interference from The Girls.
Teach her to follow through using the old dime on the barrel or slide, big, close targets and, perhaps best of all, a laser sight. With a laser, she can shoot one handed, two handed, elbow on the ground, behind her back. Wherever she can see to put that laser dot, she can learn to roll that trigger back and get good hits. Can't afford a laser? Watch for that muzzle flash. It is there, to some degree, with every load in every gun.
Tip number two, when all else fails, pay someone ELSE to train her. Sometimes we just can't teach wives or children.
