Discontinued - No Longer Available 

Combine STI's modular 2011® technology with classic 1911 styling and you get the STI Marauder.  The "double stack" set up offers the advantages of more fire power (higher capacity magazines), less felt recoil, as well as other popular 2011 features that have become a standard for competition shooting.  The classic slide is flat-topped with front and rear cocking serrations and features the TAS (Tactical Adjustable) rear sight with a Dawson fiber optic front sight.  A tactical rail milled into the short dust cover accepts all industry standard light mounts.  The Tactical magwell makes for quick and easy reloads yet still fits both the IPSC standard and IDPA boxes.  All combined, these features also produce a superior pistol for Three-Gun competitions.  The STI Marauder ships with one 140mm (20 round) magazine.
