Here's a question somewhat related to all of the Tanfo primer lighting discussions. Its in regards to the pencil test. I have several springs from PD I have tested out. In my Tanfo, or previously my Shadow, I can launch a pencil say 12"-20" above the barrel (depending on spring combos), and may get get light strikes on some of the lesser height setups. I put a pencil in my G34 and it will not even come close to leaving the barrel, yet it will light everything. How is that possible? Shape of striker vs a pin? Or because the location of striker spring vs location of FP spring?
