SOLD Lasermax G20/21
Lasermax internal laser sight for Glock 20 or 21 (Finger Grooves & Rails only).
I don't know why they specify Finger Grooves & Rails, probably has to do with how the laser is aligned?
Used for about 50 rounds by the previous owner of a pistol I just got.
With box & all parts, manual.
Digital camera is still broken, but it pretty much looks like a guide rod with a red light coming out the end.
