We have combined the best features from two of our most popular models, theBobtail* Commander and the CCO. The new Guardian has an anodized aluminumbobtail frame and an aluminum mainspring housing to help reduce printing whencarrying concealed and make it comfortable enough for full-time carry. The DutyBlack finished Commander-length slide and alloy frame give it just the right feel andbalance. If you are looking for a lightweight Commander-sized 1911 in 9mm,.38 Super or .45 ACP, don't pass up the Guardian.
