I bought a lone wolf extended ported barrel for my glock 17 a couple years ago. I wanted something that would keep discharged gas from mucking up my glock laster light. Since the ports are along the top of the barrel I thought it would be a good choice. I read customer reviews and the only problem I came across was somebody complaining that the barrel caused the gun to jam. This guy supposedly brought this issue to lone wolf and they supposedly recommended he fire more ammo through it, to break it in. And supposedly after doing this he no longer experienced malfunctions. Well the same thing happened to me so I attempted the same solution. 4 boxes of ammo and many jams later it didn't seem to have any effect. I did find that hollow points feed better than fmj's, but aside from that I saw no signs of improvement. Now I have a 120 dollar paper weight. Has anyone else experienced this? I'm pretty upset about this. Not because of the wasted money, but because these guys are selling a product that has a massively high failure rate. How am I supposed to trust my safety to something like that? How many rounds do they think I should have to fire before their barrel works right? Should I really be expected to have to do that in the first place? It's ridiculous. Anybody else experienced this issue? I'm not sure what to do about it. I haven't tried to contact lone wolf as I've never successfully gotten money back on a faulty product that I bought online, so I just never bothered. Also, I would have posted this in the ask the experts forum but my account is restricting me for doing so.
