G22, G23, G24, G27*, G35 While the S-Pro Stabilizer frame itself is compatible with GEN 5 .40 G22, G23, G24, G27*, G35 Glock models, with these models, the GEN 5 slide is not compatible with the bundled charging handle. Since the Stabilizer frame covers the slide grips, you will need an alternate way to rack the slide like an RMR or some other solution. If you have a GEN 5 slide and an alternate way to rack the slide, you can use the S-Pro. If you have any of these Glock models G22, G23, G24, G27*, G35 WITHOUT a GEN 5 slide, the S-Pro is fully compatible. * The Charging Handle is not compatible with RTF “Moon Cut” slides
