Wolff Gunsprings Ruger SP101 Reduced Power Spring Kit

This Wolff Shooter's Pak lightens the trigger on a Ruger SP101. It holds three reduced power hammer springs rated at 9, 10 and 12 lb, plus one 8 lb trigger return spring. The stock SP101 hammer spring is 14 lb and the stock trigger return spring is 10 lb, so you can step down in stages and stop where your pull feels right.

It fits SP101 revolvers in all centerfire calibers and the 22 caliber models built through 2003. It does not fit the redesigned 22 caliber SP101 introduced in 2011. Lighter hammer springs strike primers with less force, so test any combination with the ammo you plan to carry.
