Hi all
I have a stock SP-01 Shadow, DA pull was 12 lb or more
I put in a CGW 13# hammer spring, and a reduced power firing pin spring, as well as reduced power trigger spring n trigger pin. DA pull reduced to ~9.5 lb, but after some DA dry fire practices I found the firing pin was stuck, protruding from the firing pin hole. I had to slam the slide on a piece of wood a few times to get it out. SA dry fire seems fine.
A bit of searching suggested the firing pin spring may be too weak, I put the stock firing pin spring back. DA dry fire doesn't cause issue anymore. Bu
