I'm very new to the Glocks and wanted a little change from shooting revolvers. Got a G22 3gen. police trade in couple months ago and have been real happy so far with the 40SW, but liked the idea of the conversion barrels and all the aftermarket stuff available for Glocks. Today with a brand new 40-9 Lone Wolf conversion barrel, stainless steel guide rod, 15 lb. recoil spring and OEM 17 rd mags and a 33 rd. mag unknown maker. Started with a box of 20 rd. Gold Dots 124gr. short barrel hollow points, then 50 rd. box of American Eagle 147 gr. FMJ and a box of Blazer Brass 115gr. FMJ. and ending with a few reloads. All rounds chambered and fired and ejected with no to the face except for one of my reloads at the end and needed to be reracked to close the slide. I'm thing my reloads might be just a bit to light. Very happy camper with the Lone Wolf barrel and guide rod/spring and even the ridiculously long 33 round magazine.
