I recently went out shooting with a friend of mine (shot a G30, AR-15, and a 12ga. 870). It was extremely fun as I had never shot an AR before and I wasn't too bad with it if I say so myself (hitting soda cans at 80+ yards, of course I was prone). To my surprise, the G30 was very soft shooting and quite accurate. I loved it. I thought it would be too small for my large hands, but it was acceptably comfortable. Now I'm going to buy a Gen 4 G17 as my first handgun, but I am very strongly considering buying the G30 for CCW. I noticed that the slide is a bit wider than a G17, but is it uncomfortable in an IWB? I'm thinking about a CrossBreed Supertuck. Experienced CCWers please chime in! PS. What's the difference between the G30 and the G30 SF (what does SF stand for, Slime Frame or Small Frame)?
