This recoil spring assembly works for the following Gen3 GLOCK models: 20, 21, 20SF, and 21SF
Shooters looking for an upgrade from the stock recoil system will be rewarded when trying a Glockmeister tungsten recoil spring assembly. The tungsten guide rod gives 100% reliability with a unit that will never crack or break. Many shooters experience tighter groups from the increased performance over the stock guide rod. The added weight of the tungsten provides for quicker follow-up shots and less perceived recoil. We offer the ability for the shooter to have the guiderod equipped with a lighter or heavier ISMI recoil spring. When choosing a spring please keep in mind that for most shooters using factory ammunition a stock weight spring will give you the best results. Using a heavier or lighter spring may result in the gun malfunctioning. Glockmeister will not accept rod returns if you purchase the incorrect spring weight.
Like all Glockmeister products this guide rod is made to the highest standards using the highest quality materials available. CNC machined here in the United States.
