I imagine the RTF models will eventually be phased out along with the rest of the 3rd Gen line, but haven't heard anything about a timeframe for doing so.
It is a Glock. It is not rare or fancy. It will NOT appreciate in value; however, it will not depreciate much at all. Like Billy Dee says, "It works everytime".
The Gen 4 grips are pretty aggressive as well! I have a RTF Glock 22 and a Gen 4 Glock 22. I actually like them both, but would imagine my hands would be raw after 1000 rounds on the range in a day.
I had not heard that yet, although it will not surprise me since they have the Gen 4 now. I heard the Gen 4 models were not replacing the Gen 3 models, that they are just another option I really hope this is true because I do not at all care for the RTF or the Gen 4 models. I will stick with my Gen 2 and 3 Glocks.
