For a good DA trigger pull it’s important to dry fire, dry fire, dry fire and then dry fire some more.
At the range, mix in a snap cap with live rounds and it’s easy to see the shooter input without the recoil.
This is very good advice. ^^^^^
When I was teaching my ex girlfriend, starting out I'd walk her through loading a magazine, loading the weapon, chambering a round, putting the safety on. I backed off after the first range session so making the gun ready became something she knew how to do on her own. I would then stand behind her and watch her shoot and try to spot for her. Several times she would go to shoot, and forget to chamber a round, or she would leave the safety on. I never corrected her. I let her try to shoot knowing the gun would not fire.
Those particular instances really illustrated how much she was jerking the trigger. She would look sheepish and puzzled at first, but then I would shift it to "I saw this coming and said nothing on purpose so we could see how your trigger squeeze was, and because it'll help you develop automatic gun handling techniques. So it's a good thing because you can check yourself." Like I said, if you can't pull/squeeze a trigger without moving the gun all over the place, all the other stuff about technique means nothing. You'll miss every time. So in my eyes, it's the first lesson that needs to be learned, followed immediately with sight picture.
Throwing a snap cap in when she isn't looking is a good idea because it will serve the same purpose.
I have an extremely young and new workforce, and when I took over managing all 11 of them, I learned something really important as I trained them.
It's vital that you as a teacher turn failures into a positive thing for them so they understand that a failure is just another learning experience. That way they relax, and they aren't afraid to make a mistake. They understand it's just part of the process and they are positively reinforced and encouraged. The natural instinct of anyone is to observe a failure or shortcoming in their own performance, and see it as a bad thing. The teacher needs to shift it away from negativity, with any skill you are teaching.
One more thought.
She says she's not flinching and goes from SA to DA i said well that maybe the issue just shoot it DA because when SHTF you want to shoot it in DA.
This really concerns me. Cocking a hammer in a SD situation could possibly be misconstrued in court. As we all know, shooting needs to be the last option. If you have time to cock the hammer, a lawyer could make the argument you had time to run away, or that you intended to kill someone. Now, trying to prove that would be hard, and who would know you cocked the hammer if you killed your attacker. And what if you use a SA revolver as your SD weapon, as a few folks on THR do?............ but none the less, it's a bad idea I think.
My bigger concern is that she develops a habit of cocking the hammer on the first shot. If she is actually in a defense situation, and draws her gun as a deterrent, having the hammer cocked in a high stress situation could lead to a accidental discharge. Not a good scenario. If it were me, I'd emphasize SA shooting is for hunting and range time, never ever SD. If she is practicing for SD, SA shooting shouldn't even be happening.
Good luck.
