Product Description The Zaffiri Precision ZP.19BCPBN is a match-grade, chunk ported drop-in barrel engineered specifically for Glock 19 Gen 1-4 pistols. Featuring the Integrated Blowhole System (IBS) #2, this updated design combines the proven ZPS.1 slide architecture with an angled port and back-bored barrel that pushes propellant gas upward and outward, significantly reducing carbon buildup inside the slide. Machined from premium 416R stainless steel and protected by a durable black nitride finish, this barrel delivers the flat-shooting performance of a compensated setup without the need for a threaded barrel. A polished feed ramp and oversized lockup area ensure reliable feeding with lead, plated, and jacketed ammunition alike, while the flush inward crown and large ZP logo machined on the port side of the lockup reflect the brand&';s commitment to precision and craftsmanship.
