Scarlet, you are correct…
Something is not engaging the firing pin correctly.
When slip hammering a shooter lets the hammer slip off their thumb while holding the trigger back.
If the thumb drags on the hammer too much the hammer motion forward can be reduced enough to cause light strikes on the primer.
Thus causing the shooter to “ring around the Ruger”.
All these people that wish for the good old days and yet very few people help with running the clubs...
IE: writing stages, setup and tear down, building props
Come on out and help and we would be happy to shoot stages any way you like!
