Nice, my G22 is a Gen 3 as well. I am a big guy and I have tried the smaller Glocks/others to no luck. Shoot them well but they just aren't comfy. I held the regular G21 Sunday and man the grip is fat! lol. I will keep my eyes open for a G21SF, it will fit in nicely with all my other .45's! My XDM 45 shoots great but I like Glocks. Big eyes and empty pockets!!
