I was reading that the Glock 23 and 19 are going to have the RTF2 as an option soon. The Glock 23 RTF2 is supposed to be hitting the market in the late 3rd quarter and the Glock 19 RTF2 in the late 4th quarter. Also heard about a Glock with backstraps you could switch out at Shot 2010. Don't know how true these statements are, but thought I would share them. Time will tell every story.
