I just picked up my new to me shorty 45. I want to get new springs recoil-hammer-firing pin. I see that wolf does not show any springs for the 4513 are the springs for the 4516 the same for 4513 they also show 4516-1 ? Just want to make sure I get the right springs. Thanks

If yours uses the single recoil spring then it is the same as the 4513. The -1 and Shorty should use the dual spring setup that Wolff doesn't make a replacement for, I get those springs from S&W. I would get all of them from S&W unless you wanted to use a lighter hammer spring.

Thanks. yeah mine uses the dual spring I will order them from S&W wish wolf made them oh well.
