Chalk I was just checking brownells and they sell a spring pack that has the 15# recoil spring and a 20 and 18# hammer spring kit. If they haven't shipped your package out yet maybe see if that might work? In the Q&A section a tech says that the kit isn't compatible with some new p226 models so I'm not sure what to think. It may be worth a shot though. The regular price for the kit is like 17 bucks.
