I bought into the generally positive reviews of Lone Wolf Barrels for Glocks, but my experience with two recent purchases of their barrels makes we wish that I had ordered from KKM or another manufacturer. As my Pappy used to say, "If it seems too good to be true, it probably ain't."
Barrel number one - LWD standard length .45 ACP for G21. The barrel has a chamber that is ~ .003" tighter than Glock Gen 4 barrel and the case head is fully supported (nothing exposed forward of the extractor groove). High end .45 Super loads cause no excessive expansion and there are no "smileys." BUT, the chamber appears to be too short. Reloads that are within SAAMI specs and chamber in a check gauge, Glock OEM barrel and two Springfield barrels will not chamber in the Lone Wolf .45 ACP barrel. I know that I can send it in and have it reamed by Lone Wolf, but after initial purchase ($115 to have blind marked), shipping, and $30 reaming charge and more shipping, I would have been much better off to have went with KKM (or other manufacturer) in the first place.
Barrel number two - LWD 5.2" threaded 10mm for G20. The barrel has a chamber that is ~.003" tighter than Glock manufacture, but leaves 0.097" of case forward of the extractor groove exposed and unsupported. This is exactly the amount of unsupported case in the Glock Gen 4 OEM barrel. When fired with high end 10mm loads, both the Glock OEM and the LWD barrels generate lots of smileys and even bulges. I emailed Lone Wolf and their reply was, "Customer Ticket Solved - The measurements that you have are all we can offer in terms of cartridge support." So, why buy a LWD barrel when the specs (at least as far as case support goes) are no better than OEM? Note that on their website LWD touts their barrels as offering more cartridge support than OEM. (As another point of interest, I have a Glock OEM Gen 3 .40 S&W barrel and it leaves only 0.040" of unsupported case forward of the extractor groove.)
Bottom line, I have spent around $245 on LWD barrels and will probably have to spend another $375 to get barrels (from another manufacturer) that will do what I need. Your mileage may vary, some seem quite happy with their LWD barrels, I am not.
