I have a difficult decision to make. I wanted to purchase another Glock but can`t decide whether I should get another 9mm or a .40. The only thing I don`t like about the 23 is that it`s a used gun but the shop I went to was willing to give it up with 1 clip, mag-loader, a few cleaning utensils & the bbl, pins and slider are all replaced with chrome pieces for 400$. Good deal? Suggestions?
