If you're building or customizing a Glock 42 in 380 ACP, the Rival Arms RA42G003A Slide Completion Kit delivers the hardened parts you need to finish the top end of your compact carry gun. This kit is purpose-built for the G42's single-stack frame and comes with the critical components required to complete your slide assembly—saving you the headache of sourcing individual parts from multiple suppliers and ensuring compatibility right out of the box.
Built from PVD stainless steel in black, these components are designed to withstand the demands of regular carry and shooting. PVD (Physical Vapor Deposition) coating provides a durable, corrosion-resistant finish that holds up well in the field and maintains its appearance through years of use. Whether you're working on your first G42 build, upgrading an existing pistol, or looking for quality OEM-spec parts, this kit gives you a solid foundation for a reliable 380 ACP platform.
Rival Arms brings serious attention to fit and function—these parts are engineered to work together as an integrated system, not a grab-bag of generic components. If you're deep into Glock customization or just want a hassle-free way to complete a G42 slide without hunting down individual parts, this kit simplifies the job and gets you to the range faster.
