i carry a G17 on duty....i prefer my Glock 10mm but regs are regs....
what i like about the G17 is that with a rubber slip on grip i get a full sized grip with a soft shooting, good defensive caliber.
your right, i guess all other glocks are just personal preferences not really improvements over the O.G.
with Sarah Jane, Leela, Romana, Nyssa, and Tegan.
Facts are no match against enthusiasm and ignorance...
