I have a Ruger SP101 in 327. I'm looking at Wilson/Wollf Spring kit to lighten up the heavy double action trigger pull. I would like to use the 10 Ib hammer spring. My concern is reliability with the 327 since some of the ammo from some manufactures use small rife primers as do some hand-load recommendations. My hand-loads use CCI 500 primers. Would I be sacrificing reliability for lightness and maybe should use the 12 lb. spring? Any experience with the caliber, springs and gun?
