2011 9mm Open guns are stocked here from Atlas, SVI, Staccato, and Infinity, built as complete, comped race guns for USPSA and IPSC Open division competition. These pistols come dot-mounted from the factory or fitted with an optic-ready mounting platform, comped for reduced muzzle rise, and chambered in 9mm to run Major power factor loads at the velocities Open shooters need to maximize scoring while keeping recoil manageable enough for the dot to stay trackable between shots. Compensator porting, barrel length, and slide mass are all tuned together on these builds to balance flatness against reliable cycling, since an Open gun that doesn't cycle consistently under hot 9mm Major loads is worse than one that's slightly less flat. Atlas, SVI, and Staccato each bring their own frame geometry and trigger systems to the platform, while Infinity's Open guns carry a long competition pedigree at the top levels of USPSA and IPSC. No competitor in this space robustly merchandises complete Open 2011s as their own dedicated category, making this one of the most direct paths to a match-ready Open gun without assembling one from a parts list.
