No it isn't. You think it strikes perfectly each and every time with no deviation? The firing pin hits primer brass perfectly each and every time? The primer would have to concave the exact measurement each strike. It doesn't.
Does anyone really know why snap caps work?? Wow

I never claimed it hit perfectly every time did I? Matters not, the brass is going to STOP the pin from over traveling. On some pistols it matters even less because they have stop pins built into them such as Rugers Model ll & lll which I bet amounts to near the lions share of semi auto .22's on the street.
