L2D Combat Guide Rod Glock 17 Gen 3 Standard Frame Stainless Fluted Stainless. Spring interchangeability is maintained by the use of a reinforced screw at the rear of the assembly providing a clean single piece appearance. All of our guide rods feature our signature fluted shaft design and ship assembled with a premium quality ISMI recoil spring. If you intend on installing this guide rod into a Generation 4 or Gen 5 Glock pistol a reducing ring will be required. Please note: L2D guide rods will not accept the OEM factory recoil spring due to having a slightly larger shaft diameter. We only recommend running ISMI recoil springs for maximum performance service life and reliability.
