I was thinking about selling/trading in a 2nd gen Glock 19 that I have. I'm interested in getting one with the light rail. First, would you recommend selling the 2nd gen or keeping that one as well? I've seen all kinds of threads that talk about the older gens being better than the newer ones, so I'm wondering what to do. Should I try to find a 3rd gen that has the light rail and stay away from the newer ones? Also, if I do decide to sell the 2nd gen, any ideas what it's worth? I bought it used in '95 and (I know it's kinda sad), but probably only put 150 rounds through it. I'm not sure how many from the previous owner. Any suggestions/recommendations would be appreciated. Thanks.
