Pierced Primers in WW2 P.08's?

[velodog455~]

In the Research Archives forum I was reading a really good thread about drilling a hole in the underside of the breechblock to provide a vent for gas in the event of a pierced primer. The system would not allow me to reply so I'm starting a new thread.

I understand the rationale of drilling a hole for WW1 and Weimar P.08's that had the earlier unfluted firing pins but my question is did the fluted firing pins solve the gassing problem or should I use an abundance of caution and drill the vent hole for my shooter grade '41 byf?

Hope this is not a dumb question but inquiring minds wanna know. Thanx for any and all assitance.
