Tennifer metal treatment means it shouldn't rust plus it's claimed they don't use MIM parts, there is no stupid stuff on slide like: "Garrison", "Mil-Spec",.... I think it represents good value. The only thing I don't like is Cerakote finish due to bad experience with M45A1, but that gun was stainless steel so it may not be a problem with this one, i don't know. If I wanted 1911 I wouldn't mind this for price asked.
