its not worth anymore than a new one, if anything its less. pre ban means nothing with handguns, alls that matters are if the mags are pre ban. you can get preban mags easy with a little internet surfing. as far as model you said glock 17 which is a fullsize 9mm, but then you said 10mm? which isnt it, because there is no such things as a 10mm model 17…
