I had problems with the .40 cal Lone Wolf barrel I picked up to shoot lead reloads in my G-22. Like so many before me I thought the barrel switch out would be plug and play- damnably not so with the very first round FTFeed in the oh so tight chamber of the Lone Wolf barrel. I soon found volumes of information from the Glock community on this very issue- even though Lone Wolf touts ability of their product to handle lead they gloss over the issues many will find with typical range pick up brass with the slightly oversize lead bullet used for the common reloaded round. This results in a little larger than factory diameter that chokes in the Lone Wolf Chamber but is no problem at all in the stock Glock barrel. And as a side note I was full length resizing all my brass to get back to original case diameter to remove any Glock bulge, still a no go in the Lone Wolf barrel. But, blessedly, the Glock community had fixes in place, and better fixes than shipping back some dummy rounds along with your newly acquired barrel to LW to open up the chamber for additional money. This path was not going to happen as damned if I was going to give these guys any more money to fix a problem they induced. Going to school on previous posts, some of them right here on Glock Talk, my solution was as follows: 600 grit sandpaper, 3/8" wooden dowel, an electric drill, 10 minutes of carefully working the sand paper in and out of the chamber at low speed, intersperesed periodically with dropping a loaded lead reloaded round in the chamber to check progress. When I got the 'kerplunk' I knew my task was complete. I finished things off with some 0000 steel wool to polish. Off to the range with the reworked LW barrel, my G-22 now ate those lead reloads and barked its approval without any complaints. My fix cost less than $10. Now all I have to do is get rid of that unsightly Lone Wolf logo... Wanna kill these ads? We can help!
