Light firing pin strike...
My HP-22 was purchased in the mid 90's. It has work fine until recently. It seems to fire the first round after hand charging, but the second round gets a light firing pin strike, if it gets one at all. I gather the firing pin/spring combination is similar to most single action autos with an external hammer. The spring keeps the firing pin to the rear until the hammer strikes it and drives it forward. The spring then returns the pin to it's rearward position upon the hammer being re-cocked. Depending on the length of the firing pin it can either be full length or inertial (like the 1911A1). Is this correct?
On my pistol, the spring appears to be very week and if I push the firing pin manually with the tip of a screwdriver, it fails to return to the rearward position. Does this sound like just a bad firing pin spring spring?
