Product reviews: Sig Sauer Factory Recoil Spring, P239 9mm, SIGPRO 9mm, P225A 9mm - Silver

My P239 is over 20 years old and the old recoil spring is nearly half an inch shorter than the new one. The old one got tired for sure. The new black one appears to have been stress relieved in air while the original has a fancy silver finish and looks to have been peened. The original had very square and smooth ends. Looks like the product cheapening committee has done its thing on the recoil spring. That said, the new one does seem to fit and function OK.
