I didn't either. I dry fire all the time. Before and after I read that. I have snap caps now but like every one else has said it will not hurt it to dry fire.Cool ... Would love to read it ... Never heard of such a thing before.
I thought snap caps was recommended with the XD to avoid unnecessary impacts against the firing pin retaining pin.?.
That pin is a sacrificial item, and is designed to do just what you describe ... That doesn't mean you can't dry-fire without a snap cap.You are correct. Using a snap cap is recommended when dry firing. Repeated impact on the retaining pin will eventually wear it out and require you to replace it. This information comes from an armorer.
