In a time when it is difficult to get Ammo, this Glock 22 is set up with the ability to fire both .40 cal and 9mm. The 9mm wolf 9X19 Glock 22 SS barrel is installed but is very simple to swap out. Just remove one barrel and replace it with the other. There is nothing more to do but swap mags. Call me at 361 704 0297. Price is firm!!! I will take cash, NO TRADE, but you must have ID.
