Lone wolf .40 to 9mm conversion barrel for the G22. Will also fit the g23 and G27 as well. This will let you shoot 9mm out of your .40 cal glock. It's also ported so it reduces muzzle jump so shooting 9mm is very smooth. Comes with brand new g17 high cap factory magazine or you can also use your g22 mags (not as reliable as the g17 magazine). This worked great in my gen3 g22. Price is $100 OBO. Shipping is an option Item is back for sale. Thanks!
