I have both the 30 and 30 SF. I have carried both and they are one of my favorite Glocks when I'm not carrying my 1911's. A photo won't show you any real difference. You have to feel it to tell the difference, and there is some difference in the feel and grip diameter. I personally didn't have any problem with the standard 30, because I have a big set of mits. But I do like the feel of the 30 SF a little better. It feels like I can acheive a better hold on the pistol, especially when shooting hotter loads. I carry the 230 gr, Speer Gold Dot "Short Barrel" load. But either way as long as you can properly grip the gun. I think you will probably like the 30 SF a little better. Most people do that I have talked with.
