Would a 3913/3953 rod work?
Brownells says that is what S&W sent them and what they told them to label on the bag. Says "assembly" on bag. Going to give S&W a call and see if they can explain what is going on.
Maybe you're supposed to transfer plunger & plunger
spring, from old rod---see posts 17 & 18.
Wouldn't help much if you lost the old rod, though...![]()
