The P226R is the rail-equipped P226 using SIG's R-suffix to distinguish it from pre-rail variants. It added a full-length Picatinny rail under the dust cover for weapon light mounting, a feature that became standard on most SIG service pistols within a few years, rendering the R distinction unnecessary.
