Building or refreshing a Glock 42 slide comes down to the small parts hiding inside, and that's exactly what this Rival Arms kit takes care of. It gathers the full set of internal slide components into one package so you're not hunting down a striker here and a spring there. Rival Arms machines select parts from solid stainless steel billet and finishes chosen pieces with a black PVD coating, which holds up well against wear and the daily grind of carry or range use.
The centerpiece is Rival Arms' precision striker, or firing pin, engineered to tighter tolerances than you'll typically find in a bag of factory small parts. Consistent striker geometry translates to more repeatable ignition, and that steady behavior is what most folks are after when they upgrade internals. Everything in the kit is designed to work together as a matched set, so you're not mixing and matching components with different tolerances and hoping they play nice.
This kit is spec'd for the Glock 42 chambered in 380 ACP and no other model, so double-check that you're working on a G42 before you start. Installation doesn't call for a gunsmith. If you're comfortable with a Glock armorer's tool and have disassembled a slide before, you'll have this together without much fuss. First-timers should keep a good breakdown video or manual handy, since the striker safety and depressor plunger spring like to launch across the bench if you rush them.
Whether you're completing a bare aftermarket slide, doing a full rebuild, or just swapping in fresh internals on a well-used pistol, this kit gets your Glock 42 back to dependable, reliable operation with parts sourced from a single trusted maker.
This kit is built specifically for the Glock 42 chambered in 380 ACP. The G42 uses its own single-stack, small-frame internals, so parts from a G43 or full-size Glock won't interchange. If you're working on a different model, Rival Arms offers separate completion kits for those platforms.
No gunsmithing is required. If you're comfortable disassembling and reassembling a Glock slide with a basic armorer's punch, you can handle this build at home. New builders should follow a solid disassembly guide and take their time with the small striker safety and plunger springs.
PVD is a hard, thin coating applied to select parts for added corrosion resistance and wear protection. On internals that see repeated cycling, that finish helps the components hold up over the long haul. It also gives the parts a clean, uniform black look.
It works for both. Since it bundles the complete set of internal slide parts, it's ideal for finishing a bare aftermarket Glock 42 slide from scratch. It's equally handy for refreshing tired internals on a pistol that's seen a lot of rounds.
