I appreciate all the helpful replies to my question.
The reason I posed the question about modifying a non-fluted was mostly out of curiosity. Only if it could be easily done and was recommended by the experienced folks on the forum would I have attempted to do such a project. Also, I wanted to take the greatest of care of my shooter and if a fluted firing for a shooter was strongly advised, I would follow such advice.
I am a bit OCD about carefully cleaning/lubing all my guns after a range trip. Heck, half the fun I have is disassembling and cleaning all the parts, lubing and carefully reassembling everything.
So I understand that a super clean firing pin/breech block et al somewhat obviates the need for a fluted firing pin. That works for me.
