Thats odd, I didn't know they used plastic rods in the P238.
Wolff carry's recoil springs and guide rods for the Colt Mustang which are direct replacements: http://www.gunsprings.com/Semi-Auto%...ID1/mID1/dID68
I added the extra power 12lb spring and extra power firing pin spring, But haven't tested it yet but im told it will have good results.
