Factory sights fit any Glock.
- Glock rear sights are interchangeable across all Glock handguns
Standard factory sight heights:
- 9mm Luger, 40 S&W, 357 Sig, 380 ACP is 6.5mm (.256")
- 45 ACP, 10mm is 6.9mm (.27")
- A change in sight height by one increment, for example from .256 to .27, will result in a shift of approximately 2" (higher) at 25 yards, given no change to the front sight.
- Glock recommends the use of their rear sight mounting tool for installation.
