Slide Completion Kit Compatible with .40 Cal Glock Slides?

Is the slide completion kit compatible with .40 Cal Glock slides? (G22/G23)

In short, the Rival Arms slide completion kit is not compatible with .40 caliber Glock slides. Some parts are cross compatible but not everything.

 

Factory parts for the .40 caliber models are different than those for 9mm models. The extractor, firing pin, and spring loaded bearing are caliber specific.
