Question about custom barrels for G20

[Lee123]

I was at the local gun show today and took a Glock 20 in trade. The guy said it was pretty new and the serial number list bears that out since it was made about a year ago. It came with 2 extra barrels. Both are stainless. One is a Fire Dragon Ported 357 Sig Conversion and had the original packaging and info card. The other one did not have any information with it. It is engraved on top flat surface with the head of some kind of animal (a Wolf?) and 10 MM and is about 1.25 inch longer than the factory barrel.

I have two questions. Can anyone help me identify the manufacturer of the barrel with the animal head on it? And id there any problem with using either of these in the Glock 20?

I've never owned a 10mm or .357 Sig before, only the common old 9mm's and .45's, and I don't want to damage it. The prior owner seemed really into buying gadgets and this Glock looks to have been barely fired at all, despite coming with 3 barrels.

Thanks.
