I have shot the Glock platform of pistols for several years now. One of the most annoying things about a factory Glock is the springy sound it makes when working the slide. There are solutions for this and not all are created equal. In my search to build a well tuned Glock I’ve found that an aftermarket guide rod is critical.
A custom guide rod has many benefits. The main benefit is the ability to change springs based on the ammo you shoot and the recoil impulse you prefer. A custom guide rod will help smooth out the action and since many guide rods are made of metal, adding a little weight to the muzzle also helps counter recoil. In my search for a quality guide rod for the Glock platform I tried several aftermarket systems and Jager Products stood above the others in quality and workmanship.
Jager makes guide rods for many Glock pistols including the Gen4. Jager uses hardened steel with a black oxide. They also make polymer guide rods for those of you that want to maintain the light weight of the factory unit but gain the option of changing springs. Jager has the option of captured and uncaptured guide rods. The captured rod has a washer or adapter with a screw to retain the spring, the captured system makes removal and installation a snap during cleaning. The uncaptured rod comes at a little cost savings because there is less machining for the set screw but makes it a breeze to change springs. Most of the Jager guide rods use flat wire ISMI springs, but they do make some heavy guide rods that are larger in diameter and uses the round Wolff springs only. The heavy guide rods are great for the competition shooter that wants a little extra weight at the muzzle.
The Gen4 Glock has a unique new recoil system which makes a traditional guide rod difficult to use. Other vendors use a washer to fill the gap, Jager created an adapter specifically designed to fill the space and prevent binding of the system. Jager’s approach in design and function is far superior to the other offerings.
Jager doesn’t stop at just making a quality guide rod, you can also buy the matching spring direct from them making it a “one-stop shop” for a high quality system. The most common springs would be a 13 or 15 pound spring for a 9mm or .40 based Glock.
The center guide rod in the image above shows the downfall of other guide rod systems, if the rod isn’t sized correctly the spring curves and binds around the rod. A correctly sized rod keeps the spring linear which in turns creates a smoother system. If you are looking for a guide rod or spring for your Glock please head over to Jager Products and check them out.
IDPA compatibility? The standard length is legal for IDPA SSP and ESP divisions as it is no heavier than stainless steel. The heavy extended is legal in ESP only. I could argue that the heavy extended is also within the rules for SSP but it’s not similar to the factory system which is against the intention of SSP. The Gen4 heavy rod is not extended so it is fine in either SSP or ESP.
