Wolff
An 18 lb full-size recoil spring, the heavier weight Griffith Guns suggests for a 92S running the Baccano.
Wolff's 18 lb full-size Beretta 92/96 recoil spring covers the heavier end of what Griffith Guns suggests for the older 92S. That 17 to 18 lb figure comes from his install video rather than the written product pages, where he says the 92S felt like it needed a stronger than usual slide spring; the written pages give 15 to 16 lb as the general guidance. On a standard 92FS this weight is heavier than the specified 16 lb.
