Armscor Rock Rocki 51623 Ultra Fs 9Mm 5 10R Blk

The Rock Island Armory Rock Ultra FS is a 9mm single-action pistol built on a Series 70 platform—a proven, no-nonsense design favored by shooters who value reliability and straightforward operation. With a 5-inch barrel and 9+1 capacity, this full-size 9mm strikes a balance between shootability and everyday carry practicality, making it at home on the range, in a holster, or on the nightstand. The parkerized finish handles hard use without fuss, and the combat hammer and skeletonized trigger give you direct feedback on every press.

What sets the Rock Ultra FS apart is its ergonomic commitment: an ambidextrous thumb safety means lefties and righties operate it equally well, while the high-sweep grip and VZ grips provide confident control during rapid fire or precision work. The fiber optic front sight pairs with a tactical-style adjustable rear sight, letting you dial in your zero and dial in your shot—whether you're working at 7 yards or 25. At 2.49 lbs, the gun doesn't exhaust your wrist or your attention span during extended sessions.

Rock Island Armory has built a solid reputation for delivering honest, functional firearms without premium pricing. The Rock Ultra FS is no exception: it's a straightforward, capable 9mm for shooters who want the controls and ergonomics they understand, proven performance they can count on, and a platform they can shoot all day.
