Thinking about converting my G21gen4 into a 10mm

I know there are conversion barrels out there from 21 to 10mm for a G21.

However, I like get a complete original G20 glock slide for my G21gen4 frame. Is the assembled G20 slide gen3 or gen4 frame specific?

Is there anything else to convert besides a complete slide, barrel, rod/springs, & magazines?

Thanks

    I did the same thing with my G21 and slapped a complete G20 slide , both were gen3....and got 10mm mags.

     

    I think you can put a gen3 slide on a gen4 frame but not the other way around.

     

    There is no G20 gen 4 yet i believe.
