I've rented a Gen 3 Glock 23 with RTF and I loved it. I like the Gen 4 grip even more, so I'm pretty confident I'd love it. I'd shoot an FN if I could, but there's only one shooting range in the area and it only rents Glocks, Rugers and FDs. I've also yet to see anyone go to the range with an FN, so I've been completely out of luck there. I think I'm leaning towards the Glock now, if nothing else just because of the endless reputation and support for it. Pics when I get it.
