In addition to the hammer assembly, the kit includes the mainspring, the ambidextrous safety assembly, and an extra power plunger spring. |
Maybe there's no firing pin, maybe it's broken, or perhaps the mainspring is weak. |
The actual percussion lock has been modernized to include a coil mainspring and parts proven reliable and trouble-free. |
Lifting the bolt handle to extract the fired case and compress the mainspring is very difficult. |
I would be very careful in replacing a mainspring with one that is less than half as strong as the former. |
I did get a few misfires, so I believe a stronger mainspring or perhaps a longer firing pin or both would take care of this. |
