Analysis

Rock Standard sits one step above the GI line: Series 70 lockwork, rubber grips, and skeletonized controls without the G10 and adjustable sights of Rock Ultra. Full-size parkerized guns remain the core SKU. Nickel and two-tone shorter-slide guns and a parkerized mid-size listing filled out the family. It is the volume Rock 1911, not a railed TAC pistol.
