NDZ 13LB Guide Rod Assembly Stainless Steel Adapter for Glock GEN 4-5 19 19x 23 32 38 45

Designed to fit Glock Gen 4-5 Models: G19, G19X, G23, G32, G38, G45.

Replace the fragile polymer guide rod assembly in your Glock with a purpose-built stainless steel assembly engineered for real-world use and abuse. This NDZ Performance 13 lb. guide rod assembly removes guide rod flex, improves slide lock-up, and gives you a tunable platform for consistent cycling and faster sight recovery. Durable, tunable, and built for duty; swap the weak link for an NDZ guide rod and get predictable, repeatable performance.

Eliminates guide-rod flex for firmer slide lock-up and more consistent timing. The built-in adapter ring corrects Gen 4/Gen 5 pistols spacing so the single-spring assembly sits parallel to the barrel for better performance. The hex-screw removable end cap lets you swap recoil springs quickly; allowing you to tune your ammunition and spring pairing without replacing the whole rod. Comes with a 13 lb. recoil spring installed (stiffer than stock on many sub-compact setups) for controlled slide velocity and reliable feeding. Get yours at NDZ Performance today!

Features:

• Precision stainless steel body: corrosion resistant and won’t chip or crack like polymer.

Note: We recommend the use of Blue Loctite on the hex screw threads when switching out springs. This will provide a firm hold and still allow easy removal when necessary.

ISMI premium springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then the springs are heat treated, shot peened and stress relieved after winding to enhance performance and durability.

Note: NDZ always recommends any part be installed by a qualified and trained gunsmith. NDZ promotes the use of safety practices and gear when working on any firearm.
