I can't stress enough about the importance OS dry fire training.
My friend and I were at the range today and he had some trigger issues that we worked on. This was his 2nd time shooting pistols. I showed him he should squeeze like he's shaking someone's hand and to only allow the trigger to come forward just enough to reset. The stance issues were easier to show and get figured out. The only issue remaining was the nuances of trigger control.
We got back to the house and I took the 1911 apart to show him the parts. Then I showed him trigger control techniques with the gun mostly apart. Seeing the trigger interact with the fire control mechanisms (sear, beaver tail etc) really opened his eyes.
After reassembly, safety checks and numerous "get your booger hook of the boom switch", he started to really understand what I tried to explain at the range.
I hope he'll get back soon enough to try them out with live ammo!
