The 30sf is the short frame with less hump on the back. The 30s effectively uses the slide from the single stack glock 36 to give it a similar overall profile to a g19.Is there a diff between the S and SF?
I have a gen 3 SF, put night sights on it today. Going to start off with this as my carry and see how it feels. Footprint is about the same as a 19, just a little thicker.
