Discontinued - No Longer Available

Not only is the Guardian a great carry pistol, but the good looks of the stainless steel slide with traditional 1911 styling set it apart from its competition in the 1911 market.  STI builds this pistol on an officer-length cast frame with a stainless steel slide and a 3.9" fully supported and ramped barrel.  They add a Recoilmaster for increased reliability and the low profile, adjustable TAS rear sight for more precise sight in.  With compact design, full-size power, and smooth reliable functioning, this is one good-looking pistol you can rely on.
