I'm looking to sell my gen4 Glock 23, it comes with three mags and back straps as well as the original box. I will need to see a CPL and WDL as well as fill out a bill of sale for my records only. My only trade interests would be a Sig P229 (I can add cash to even the deal) or a gen4 26 or 17. Cash price is $500. I'm located in the Seattle area.
