I did a lot of searching and there is a lot of info here but I am a bit thick and did not get convinced on the varied answers. I am running the Dual Spring Short Guide set up in both my Delta 10mm's and really do not want to change what is working. I was lead to believe the Larger Spring has a Rating of 16 Pounds and the Smaller Spring (7lbs?) which makes up the total desired of 23 Pounds, Is that correct? Plus I may want to try a 20lb (total) spring to reduce potential frame/slide pounding. Which brings up the next question - would I replace with a Long Spring rating of 13 LBs + the 7LB to make 20? Not sure that is how it works but I would like to know. Wolf rates everything but my Colt replacement springs do not have the poundage listed anywhere, not the packaging or the website. Just want to know what is stock in case I want to order from Wolf next time, and or experiment with reducing the Return Spring rate.
