Post 1998 J frame Smith & Wessons

[Seven High]

I was reading the Midway catalog about Wolff gunsprings. They offer a spring kit for pre 1998 j frames. My question is: What happened in 1998 to the j frame that precludes using ehe Wolff spring kit in them?

Nothing.

All J-Frames have always used the same spring since they came out in 1950.
The only ones that are different are the .22RF models which use a stronger spring.

Wolff makes no mention of it.
