B~T STA-TITE Sta-Tite Guide Rod for the G20, G21, G21SF.
The factory supplied plastic guide rods can and do chip. They can and do melt during repeated firing. The capturing button can and does pop out. Murphy’s law being what it is, one of these weaknesses may present itself at the worst possible time. Middle of a match? Middle of a defensive situation? Why take a chance? Replace it now with a part designed and proven to be 100% reliable!
Which spring? All B~T Sta-Tite Guide Rods are designed and intended to be used with the factory spring for ultimate reliability. Some shooters prefer heavier or lighter springs depending on their loads, recoil preferences or the addition of other accessories such as suppressors or compensators.
Any 6mm I.D. spring designed to be used in the G20 will work on a Sta-Tite rod.
