This is a very nice all original Glock Model 20 pistol. Mechanically this pistol works great.  I have personally fired it and it functions flawlessly.  This is a tried and true 3rd gen pistol.  It comes with one original 10 round magazine.  This pistol will make an excellent home defense pistol being chambered in the powerful 10mm cartridge.
