firing pin stop

Thank you for the pic.As I understand the prototypes had flat bottom stops and
the militari specified the change to a radiused leading edge.I have to say that
they were right on this one,the prints available to me call for an offset .220" R
leaving a 1/32 +/- flat I could not say how a different radius would make a difference .220" is probably tried and true.How the rounded edge affects momentum is logical,more slide leverage thru longer contact,clear mechanical
advantage and smoother action compressing the main spring.I can;t make out
the edges very well but I get the idea don't need the loupe for this one.
