There are multiple styles of handguns and firearms but the Rock Ultra HC from Rock Island Armory stands alone. So much tradition comes with this adjustable sight Rock Island M1991 10mm firearm. Designed and produced for Rock Island Amory in the USA by parent company Armscor, a Philippine based manufacturing facility that is loyal to the 1911 template.

  • Color: Black Parkerized
  • Action: Single
  • Barrel Length: 5”
  • Barrel Type: Button Rifled
  • Capacity: 16 + 1 Rounds
  • Sight Style: Fiber Optics Adjustable

With roots going back as far as the year 1911 from the original Squires Bingham & Co. manufacturing plant that was forced to shutter its door during invasion and occupation during WWII, Squires Bingham and Co. opened its doors again under the Armscor banner in 1952 and has been producing handguns for American distribution ever since.

Not only does the Armscor Company hold the contract for the M1991 handgun, but it produces guns such as the STI Spartan Cimarron and Auto Ordnance 1911 pistols.

If you’re a fan of the 1911 series you already know this Rock Island M1991 Ultra HC is a solid performer and is noted for having the most reliable performance, most affordable and is by far, the best made 1911 model firearm on the market today. The Rock Ultra full size HC is manufactured around the original 1911A1 format, often referred to a Series ’70 firing system. So if you’re a 1911 purist, knowing the pistol contains either a firing pin or hammer drop safety adapted from the Colt Series ’80 firing system is a big plus.

The thumb paddles are wide enough for easy thumb operation of the thumb activated safety and the upswept beavertail configuration allows for a closer grip to the axis of the bore, which minimizes the felt recoil. An additional feature of the beavertail safety is helping to prevent the risk of that nasty thing known as slide bite and improves accuracy downrange. With both the hammer and trigger pull skeletonized, the harmonized low-mass design reduces lock time, but also provides an extremely smooth trigger pull.

Such a well built and classical piece, the overall Parkerized finish and G10 tactical grips gives the Rock Ultra full size HC a tactical, take-no-prisoners look which almost shouts dependability and efficiency. When it comes to target acquisition, the Rock Ultra offers a low profile, snag-free adjustable sighting system. While some doubt the effectiveness of a full length sight many shooters consider it a necessity for reliability and accuracy.

Either way, it’s all about hitting what you aim at.

Manufactured from 4140 ordinance grade steel and built to last, the Ultra full size HC provides the shooter many years of dependability and consistent round deployment. For the low price The Ultra HC continues to be a solid workhorse you can count on.

I was wanting a 1911 in 10mm, really wanted a Kimber Black Ice Rapide but could afford the RIA .
Best decision I made.
Out of the box was awesome! No jams, no failure to feed, no stove pipes.
It cycles any ammo I ran through it.
After the poor reviews and videos on Kimber Rapide decided to pick up a Colt Delta Elite to see if a higher end 1911 was any better... nope just as good and for 1/2 the money.
Rock Island makes awesome products and I haven't had one problem with any of collection.
