Received my (used) Glock GTL 21 tac-lite/laser-sight today. It works very well, and the laser is visible even on an almost-white target with Arizona-desert sun shining on it.
The laser-sight adjustments are very coarse-threaded--a quarter turn moved the dot more than a foot at 10 yards. (Fortunately, I was just smart enough to figure out how NOT to shoot my chrono-screen shades.) I learned quickly to make very small adjustments, and the laser and the 'iron' sights are now dead on...at least as closely as I can hold with a rest.
