NDZ Guide Rods are fully serviceable and feature dual hex sockets, allowing quick and easy disassembly for hassle-free spring replacement by the user.

NDZ Performance stainless steel guide rods provide a decisive advantage for all Glock owners. Special features include a rigid stainless steel body that improves lock up by completely removing "guide rod flex". The hex screw removable tip allows the user to choose various spring weights that will calibrate the ammunition to his gun. Used by Law Enforcement and competitive shooters worldwide, will not chip or crack like the factory plastic guide rods are prone to do. Will not damage or wear your polymer frame and guaranteed to provide a lifetime of reliable service.

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

ISMI Recoil Guide Rod Springs

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.

ISMI Recoil springs are the best direct replacement for Glock factory OEM springs.

Independent tests reveal ISMI recoil springs have endured an excess of 100,000 compression cycles! ISMI springs include a 12-month manufacturer's replacement warranty, however we advise you practice routine maintenance and change your recoil spring yearly.

What Recoil Spring Weight do you need?

• 11 - 13 lb Spring: Competition Shooting, or with a Recoil Compensator
• A lighter recoil spring allows faster recoil time, aiding target re-acquisition
• 14 - 16 lb Springs: Reduced Power Ammunition Loads
• 17 - 18 lb: Glock Factory Weight Recoil Springs
• 19 - 24 lb: Heavy Power Ammunition Loads +P or +P+
• Please ensure you are using the correct loads for the springs to avoid cycling issues.
