Drops onto Glock 43X slim-frame pistols with no fitting or slide work. The Zaffiri Precision Integrated Blowhole System (IBS) blends their ZPS.1 slide with the Blowhole Compensator design — vented gas ports machined directly into the slide rather than bolted on at the muzzle. That trims muzzle rise and keeps the sight picture flatter without adding overall length or requiring a threaded barrel.

Machined from billet 17-4 stainless steel and finished with a Black Cerakote slide over Gold accents. The RMR optic cut accepts Trijicon RMR-footprint red dots (Trijicon RMR / RM06, Holosun 407C/508T with an RMR plate).

• Fit: Glock 43X (single-generation slim frame)
• Slide: ZPS.1 base + Integrated Blowhole System (compensator integral to slide)
• Material: billet 17-4 stainless
• Finish: Cerakote Black slide / Gold accent
• Optic cut: Trijicon RMR footprint (6-32 × 1/3" plate screws, 6-32 × 7/16" optic screws)
• Ships as a complete Zaffiri assembly with barrel and internals installed

Break-in: run 100–150 rounds to seat the barrel and IBS gas system, and confirm point of impact with your chosen optic before carry use. Not compatible with Glock 43 or Glock 48 frames — 43X only. Not compatible with suppressors — the Blowhole vents forward-facing gas from the slide.
