If your Sargent cylinder is a standard cylinder there are usually no security pins. Sargent usually uses very long top pins and bottom pins that are round instead of pointed where they meet the key. They are otherwise normal in all aspects of pin tumbler locks. Sargent does use a different slope angle between cuts and duplicates are often difficult to make accurately. This can also lead to a difficult combination where a small pin is shielded by a long pin. This makes normal picking very difficult.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
