The Brazos 5″ slides are machined of barstock 4140 steel heat treated to 38-42 Rockwell Hardness. Slides are available in the classic profile (scalloped front) or the unique profile (block front). The unique profile matches the Brazos 5″ long/wide frame, whereas the classic style matches nicely with the Brazos Short/Wide frame. These slides are bald, meaning they contain no cuts, serrations, or logos. All slides include the cut for the reverse plug.
