The RSI Swiss K31 Firing Pin, For years owners of the classic Swiss K-31 have had to worry about a source for replacement parts fro their rifles. The RSI firing pin is a direct replacement for the original Swiss K-31 part but we take the extra step to harden the steel in these these firing pins to make them better than the original. You can pair this with our K-31 firing pin spring and get the maximum performance from your K-31 bolt.
