I know they made a Glock 21 Gen 3 SF. But do they make the 21 Gen 4 in a SF?
Looked around and can't find my answer.

No, the gen4 Glock has slim frame grip and comes with extra back sections to make it thicker.  If you worried that it will be too big, leave the back sections off and it'll be similar to the SF models.

The gen 4 with no backstrap IS an SF.
