Not for my S&W but for Dan Wesson Pointman.
It is a older model and I think when I first got it used I put a new recoil spring in in. Not sure what weight(think its 18) but compared to my other 45 Autos it is really hard to pull the slide back. It functions fine but if I get a jam or stove pipe it's really hard to pull back and clear it.
I looked at the Wolf Spring selection and they have springs from reduced 7-15 lbs
standard at 16 lbs and
extra power 17-28 lbs.
I gather the wide range is for different loads but that seems like a huge range?? 7 to 28 lbs??? When would a 7 lb spring be used??
Anyway, I load low to mid range ammo, never max so would the standard 16 lb be correct or one of the calibration reduced power packs which has several and I could mess around with them?
