ZP Integrated Blowhole System Complete Upper — Glock 43 43X

A purpose-built complete upper engineered to control redirected gas and reduce muzzle rise without requiring a threaded barrel. The Integrated Blowhole System blends a proven ZPS.1 slide platform with a matched Blowhole compensator into a single, pre-installed assembly to deliver the flat-shooting benefits of a compensated setup while preserving a compact, threadless profile. Single billet 17-4 stainless steel construction and tight machining tolerances promote consistent lockup and repeatable accuracy, and the slide ships pre-cut and pre-coated with no further modification options.

Built and finished in the USA at the manufacturer’s Florida facility, the upper is optimized for Glock 43 and Glock 43X lowers and includes a compatible recoil spring assembly to simplify installation. The integrated compensator redirects high-pressure gases away from the shooter, reducing felt muzzle rise and helping maintain sight picture for faster, more controlled follow-up shots. Durable coating and robust stainless construction provide long service life under demanding use while preserving factory ergonomics and slide function.
