How rare and how valuable is a first gen Glock 17? I was in the market for a 17 MOS for carry optics, I already have a 1st gen glock 17 and was thinking about a trade but was surprised to see some selling for around 2k is that the normal now days? what is the desire for the 1st gen? just collector value? personally I always liked the smooth grip, but the gen5 seems to have that now. any glock guys here?
