Drop-in 9mm replacement barrel for Glock 19 — fits all generations (Gen 1 through Gen 5) with no fitting or modification required.
Machined from 416R stainless steel and finished in black nitride. Chamber cut and hood geometry match OEM Glock 19 factory dimensions for headspace and lockup — no gauging required.
Break-in: run 100–150 rounds before evaluating accuracy — the bore polishes in with initial firing.
