Rock Island 51815 | M1911 GI Standard FS .38 Super 5″

The Rock Island (Armscor) M1911 GI Standard FS is a traditional full-size 1911 design chambered in .38 Super with a 5″ barrel and a black parkerized finish. It retains classic GI lines with smooth wood grips, a beavertail safety, and fixed low-profile sights suited to holster carry and quick presentation. The platform’s balance and factory trigger pull make it appropriate for range training and target or competition shooting. For an optic that pairs well without exceeding a $1,000 budget, consider a small-frame red dot such as the Trijicon RMR Type 2 for reliable footprint compatibility and sight acquisition.
