The RTF and RTF2, were as you all know, never considered a generation by Glock. It seems like somebody from Glock told me the OD guns were being discontinued, but I'll have to confirm that.
The Gen4 pistols pretty much make the RTF pistols an afterthought. I expect that if a large enough contract came down the line specifying RTF/RTF2 that Glock would produce them. They were producing Gen2 pistols by contract for a rather large agency at one time even after the Gen3 guns were standard. That agency has since switch caliber and is in Gen3s.
