Description
If you have put a red dot on a Glock, or a suppressor in front of one, the factory irons disappear. The Trijicon Suppressor Sights Glock 17 19 set is Trijicon GL201-C-600649, built tall specifically to solve that. Same tritium lamps and same fitment as the standard height set, but raised enough to sit in the bottom of an optic window or clear a can.
Why Height Matters on the Trijicon Suppressor Sights Glock 17 19 Set
A slide mounted red dot raises your aiming reference about half an inch above the slide. Standard sights sit below that window, so if the dot dies you are left staring at an empty screen with your irons hidden underneath it. Suppressor height night sights fix this by sitting high enough that the front post and rear notch land inside the optic window. That is what people mean by a lower third or absolute co-witness with a red dot, and it is the difference between a backup that works and one that is decoration.
A suppressor creates the same problem from a different direction. A can with an outside diameter much over an inch will block a standard front sight entirely. The Trijicon Suppressor Sights Glock 17 19 set clears typical pistol suppressor bodies, so your sight picture stays usable with the can mounted. If you are running a very fat host or a booster with an oversized rear cap, measure before you order rather than assuming.
Construction is unchanged from the standard Trijicon sets. Both sights use green tritium three dot sights geometry with a white outline ring around each lamp, a sapphire jewel cap spreading the glow, an aluminium cylinder around the glass and a silicone cushion underneath to absorb slide shock. You are paying for height, not for a different lamp.

Honest Notes on the Trijicon Suppressor Sights Glock 17 19 Set
Do not buy these for a plain slide. On a Glock with no optic and no suppressor, tall sights give you a higher sight picture, a bigger sight shadow and nothing in return. They also change your point of aim relationship, and they look wrong. The Trijicon Suppressor Sights Glock 17 19 set earns its keep only when there is something on the gun that a standard sight cannot see past.
Holster fit is the practical catch. Tall sights ride higher in the sight channel of a kydex holster, and a snug channel that was fine with factory irons can drag or scrape the front post. Most modern optic ready holsters have the clearance. Older leather and budget kydex often do not. Check before you commit, particularly if you carry appendix and rely on a fast reholster.
Tritium still decays. Half brightness at roughly twelve years applies here exactly as it does to every other tritium sight, and Trijicon warrants the lamps for twelve years on that basis. Installing the Trijicon Suppressor Sights Glock 17 19 set is the same press fit job as any Glock sight, and the taller front post gives you more leverage to bend something if you try it with a punch and a hammer. Pay a gunsmith, then confirm zero on paper, because tall sights change point of impact noticeably at distance.
