Key Features
- 5-inch button-rifled barrel — WHY IT MATTERS: delivers consistent accuracy and tight groupings at the range, with a full-length guide rod reducing felt recoil for faster follow-up shots.
- Ambidextrous thumb safety — WHY IT MATTERS: left-handed shooters get the same positive control as righties, making this 1911 a true ambidextrous platform for service or competition.
- Fiber-optic front sight with adjustable rear — WHY IT MATTERS: high-visibility green fiber picks up light fast, and the adjustable rear lets you dial elevation and windage for precise point-of-impact.
- G10 tactical grips and beavertail frame — WHY IT MATTERS: aggressive G10 texture locks your hand in place under recoil, while the beavertail prevents hammer bite and promotes a high grip for faster follow-ups.
- Skeletonized hammer and trigger — WHY IT MATTERS: reduces lock time and trigger pull weight, giving you a crisp break with minimal overtravel for better accuracy in rapid fire.

FAQ
What type of ammunition does this 1911 shoot reliably?
Per manufacturer specs, the Rock Ultra FS is designed for 9mm Luger (9x19mm) ammunition. Most shooters report reliable function with 115- and 124-grain ball ammo. Some hollow-point loads may require a break-in period or feed ramp polishing for 100% reliability.
Is this pistol compatible with standard 1911 holsters?
Yes, it fits most 1911 holsters designed for a 5-inch barrel and full-size frame. The ambidextrous safety may require a holster with a cutout for the right-side lever.
How does the parkerized finish hold up over time?
Parkerizing is durable against rust and corrosion but can show wear from holster carry and handling. It’s a matte finish that can be touched up with cold blue or re-parkerized if needed.
Can I swap the sights for night sights?
Yes, the front sight is a standard 1911 dovetail mount, and the rear sight is adjustable. Many shooters replace the fiber-optic front with a tritium night sight and keep the adjustable rear.
What is the trigger pull weight out of the box?
Per manufacturer specs, the trigger pull weight is approximately 4-5 pounds. The skeletonized trigger and hammer reduce lock time for a crisp break.
