Hi all! New member here and I have a question. I'm thinking of trading in my 17RTF2 for a 30. Does the Glock 30 come with a rail or is that only for the 30sf? I've seen a bunch of comparison pictures showing each side by side and every one shows the 30 without a rail and the 30sf with a rail. Are these just older models without the rail or do they no offer it? I've held both and can' really tell a difference (don't remember seeing a rail on either though) in the grip, so I'm just looking for a railed one for my Surefire X300. Thanks!
