Anyone seen these yet? Shown is a 4th Generation Glock 22. Differences are cosmetic. The rear cocking serrations, and the grip stippling has been redesigned and described as "mini pyramids." Glock calls it the "RTF" frame- (Rough Textured Frame). Supposedly they haven't made a concrete decision on wether they are going to put both versions, RTF2 & RTF3 into production. (RTF3 is same design as RTF2 only it has a rougher texture because the "mini pyramids are slightly larger and slightly more raised). I still think Glock should have when with interchangeable backstraps.
