Rock Island Armory Rock Ultra CS-L 45 ACP 3.6" Barrel 7+1 Rounds

The Rock Island Armory Rock Ultra CS-L delivers full-size 45 ACP performance in a compact carry package, combining an aluminum frame with steel slide construction for optimal weight distribution. This commander-sized 1911 addresses the common trade-off between concealability and shootability that many compact pistols struggle with.

What Makes This Different

The CS-L features an aluminum beavertail frame that reduces overall weight while maintaining the structural integrity needed for 45 ACP pressures. Unlike polymer-framed competitors, the aluminum construction provides consistent lockup and enhanced accuracy potential. The 3.6-inch barrel length strikes the optimal balance between velocity retention and concealability, delivering approximately 850 fps with 230-grain ammunition compared to 800 fps from typical 3-inch barrels.

Key Features

• Aluminum beavertail frame with black anodized finish for corrosion resistance and reduced weight
• Serrated black Parkerized steel slide with enhanced grip surfaces for reliable manipulation
• Black and gray G10 grip panels providing superior traction in wet conditions
• 7+1 capacity with standard 1911 magazine compatibility
• 3.6-inch barrel optimized for concealed carry without sacrificing ballistic performance
• Standard 1911 trigger system with crisp break and short reset
• Dovetailed front and rear sights for easy customization

The Rock Ultra CS-L performs consistently across various applications, from concealed carry to competitive shooting. The aluminum frame construction reduces felt recoil compared to steel-framed alternatives while maintaining the accuracy potential that makes 1911 platforms popular in precision shooting disciplines. The G10 grips provide secure handling during rapid fire sequences, and the Parkerized finish resists wear from regular holster use.
