Awaiting a new to me 4516-2 looking for holster recommendations also recoil spring recommendations thanks group
As I recall the 4516-2 has a dual recoil spring setup using a small diameter guide rod (unlike the 4516 and 4516-1 which use a single spring with a standard diameter guide rod).
The factory Inner (108670000) and Outer (108660000) springs are readily available. Same as 4513TSW, 457, 4013TSW, and late 4013 with dual recoil spring setup.
There is also a dual spring set from Sprinco p/n 45162 but I believe it is same spring rate as S&W Factory springs.
If you are looking for alternate rates, I am not sure what might be out there in dual spring configuration.
