Armscor Rock Rocki 51585 Ultra Csl 45 3.6 7R Blk

The Rock Island Armory Rock Ultra CS-L is a compact 45 ACP 1911 built for shooters who want genuine stopping power in a carry-friendly package. This is a true single-stack .45, not a modern polymer design—it's rooted in the proven 70-series 1911 architecture with an aluminum frame that shaves weight without sacrificing reliability. At 1.72 pounds and just 7.34 inches overall, it's a serious defensive pistol that stays manageable in appendix or waistband carry, and it's Maryland compliant if that matters where you operate.

Rock Island has equipped the Ultra CS-L with practical, real-world features that work the first time you press the trigger. The 3.7-inch button-rifled barrel and full-length guide rod ensure consistent point-of-impact and longevity. You get a fiber optic front sight paired with an MPS1 adjustable rear sight—both setup to help you hit what matters. The trigger breaks at 4 to 6 pounds with an adjustable overtravel screw, so you can dial in the exact break you prefer. G10 grips give you a secure, aggressive purchase in any condition, and the parkerized slide paired with black anodized frame delivers a toughened finish that handles daily carry and range time without fussing.

This is a gun for concealed carry, personal protection, and precision range work. If you've been hunting for a carry .45 that doesn't require you to learn a new manual-of-arms, the Ultra CS-L speaks the language every 1911 shooter already knows. Seven rounds in the magazine—all you need, but meaningful for a defensive round.
