Shop for Armscor/Rock Island Armory-Rock Series online at

Rock Island Armory’s Rock Series takes the M1911 Series 70, incorporates new modern features as well as very modern production and manufacturing. The series spans .45 ACP, .40 S&W, 9mm and 10mm. It then provides this in many sizes, sights, color finishes and more. The result, per Rock Island Armory or RIA for short is, “most well optioned line of 1911 pistol built in the traditional 70 series design.”

Despite its all-American name, RIA is a division of Armscor of the Philippines. That county’s interest in M1911s goes back to the gun’s earliest days when it was often used there.

Rock Island builds all 1911s including its Rock series guns with banging tough 4140 ordnance steel. Part production is processed using automated computerized CNC machines programmed using CAD / CAM, etc. This creates very precise parts that are then hand-fitted with utmost attention to detail and tight tolerances. The result is impressive.

The Series includes many models you’ll find further detailed here at including:

  1. Stainless Steel 1911 CS 45ACP “ECS”
  2. Rock Ultra CS-L
  3. Rock Ultra CCO
  4. Rock Ultra MS – 45 ACP
  5. Rock Ultra FS – 45 ACP
  6. Rock Ultra FS – 40 S&W
  7. Rock Ultra FS – 9mm
  8. Rock Ultra FS – 10mm
  9. Rock Ultra FS HC – 10mm
  10. Rock Ultra CS – 45 ACP
  11. Rock Standard FS – 9mm

  13. Rock Standard FS 2-Tone – 45 ACP
  14. Rock Standard FS – 45 ACP
  15. Rock Standard CS – 45 ACP
  16. Cerakote Gun Metal Gray

Whichever you get, you will see common attributes such as a nicely upturned beavertail, skeletonized loop hammers, adjustable overtravel stop skeletonized triggers, dovetailed sights, etc.

The front sights are typically red fiber optic sights. The rear ones are usually cantilevered and ramped low-profile types, giving you improved usability and a better sight radius, which leads to higher accuracy. With a couple of exceptions, the entire Rock series also includes ambidextrous grip safeties and splendid G10 polymer grips.

So, there you have it. If you’re interested in a modern, high-quality, upgraded Series 70, Rock Island Armory’s versatile Rock Series is a great place to start.
