Thomme,
I’m not concerned about it. I dry fire, and have done so for years, to practice trigger control and to overcome jerking or flinching. I always figured that if I did break a firing pin I’d just fix it and go back to dry firing.
Why I posed the question is because I’ve many times heard, “Don’t dry fire! My cousin’s uncle had a friend whose wife’s father’s fifth cousin did that and it broke the firing pin”.
I have not, until rbernie’s post, ever heard a first hand account.
I’m curious, that’s all.
