I am attempting to remove the firing pin on a Sig Pro 2340. In the past I have removed the firing pin retaining pin and disassembled the slid. I found info on the proper procedures online last time. I have been unable to find any info this time. So the question to you gun smiths is, what direction to I push the firing pin retaining to in. Looking at the back of the slid as if I was shooting it. Do I push the pin to the right or to the left. One side of the pin has groves in it, I suspect to keep it from turning or coming loose. The other side has no groves and looks like it has a taper to it.
