Anyone think my G20sf slide, barrel and mag will work on a Gen4 G21 frame?

Not sure. Sounds like a tempting combo.

It absolutely works. I bought a 20SF, then bought a 21 slide/barrel/recoil assembly. Now I have two calibers. It also gives the option of these calibers, using stock or conversion barrels:
10mm
357 Sig
40 S&W
9x25 Dillon
45ACP
400 Corbon
40 Super

EDIT: The Gen 3 slide WILL NOT fit a Gen4 frame. It has to be a Gen 1-3.
