I guess mine was different, I had pins in myfinger, they couldn't reset it because a bullet went through the nuckle.
There was no shooting with that hand regardless of what finger you used, the recoil killed me. I couldn't even shoot rifle or shotgun. If I shot, it had to be a pistol/revolver with my left hand.
Every since then I've been practicing with my left hand.
As I said, that was in 1977, damp cold still gets to me.
