Alright,
I've used both the C&S firing pin and the Apex and can get a lighter pull with the C&S, so I use them. The C&S firing pins have a more blunt tip compared to the Apex with the wedge shaped tip, that probably has something to do with how much main spring tension needs to be applied to maintain reliability, but I haven't looked into that much... I have had one C&S break but that was before they started to step up the quality of their manufacturing process. There new pins seem to be just as durable as the Apex.
Also I dry fire my revos without snap caps with the C&S firing pins and never have had any problems. Maybe because I trim down the firing pin spring a little bit?...
