I just got a Lone Wolf 9mm conversion barrel for my G27 off ebay, and I've never seen one marked this way. It has a standing wolf, shooting a pistol. I admit to being new to Glock, and haven't seen a lot of Wolf barrels, but the ones I have seen dont look like this one. It was listed as being for a Gen 3, and I assume its older. Is this just the way they used to be marked? Also, like the Lone Wolf 9mm conversion barrel I bought for my G22, it has no caliber designation, and no other markings of any kind. That seems odd to me.
