The assembled rear serrated nitride slide Glock 43 43X fixes the one thing everyone hates about factory 43 slides: useless serrations. First, we machine 416R stainless steel. Then we cut aggressive rear-only serrations that actually let you rack the slide one-handed. After that, we run the entire slide and barrel through black nitride (QPQ) treatment. Consequently, the finish stays matte, hard, and corrosion-free for life.
Next, we install factory-height black polymer sights, a polished-feed-ramp match-grade barrel, and the correct dual-spring recoil assembly. Finally, every single assembled rear serrated nitride slide Glock 43 43X gets hand-cycled and live-fire tested before it leaves the bench.
What’s in the box:
- Aggressive rear serrations (much deeper than OEM)
- Full black nitride on slide + barrel
- Match-grade 416R nitrided barrel
- Factory-height polymer sights installed
- Complete recoil assembly & channel liner
- Test-fired guarantee + lifetime warranty
Because we do all this work up front, you simply strip your frame, drop on the new upper, and carry the same day.
