I have a list on wire diameter/spring weight for full size 1911's. Not sure where I got the list. If it was here or on an internet wandering somewhere. I find it handy for referencing what spring is in my gun. Is there a wire diameter/spring weight list for Commander size pistols? I assume that the wire diameter is different for Commander size pistols as the length of the spring is different. It gets frustrating as I have a Ruger 9mm Commander. The owners manual only specs the recoil spring as Item (8). No spring weight is given. I checked Ruger's Parts list online, and it doesn't even list a Commander Spring. I may play around with spring weights in the future, but that is hard to do when you don't know what the starting point is. Any info out there that gives wire diameter/spring weights for the shorter Commander length springs would be helpful.
