New Wolff springs installed in my Colt Mark IV series 80 Government .380 how will it run now?
This video details the installation of Wolff springs in a Colt Mark IV Series 80 Government .380 pistol. The user replaced the recoil spring with a 12 lb Wolff spring and a corresponding firing pin spring. Additionally, the magazine springs were upgraded with +5 lb springs for three magazines. The owner reports an improvement in performance, but notes that the firearm still has issues with Fiocchi ammunition. They are considering a 13 lb recoil spring as a potential solution but acknowledge that the ammunition might be the root cause.
