3 pages of results searching "CS45 recoil spring" (or try CS40 - same recoil spring) - go to top of Forum Smith & Wesson Semi-Auto Pistols - right corner search block. Old problem. Good info below link, but lots of others I did not examine.
Noodling around on the internet this morning and ended up finding a company called ISMI Springs that manufactures flat wire recoil springs.
Has anyone ever reached out to see if they’ll make a batch of CS45 springs?
