Trijicon Suppressor Sights Glock 20 21 Solid Night Set

Description

The Trijicon Suppressor Sights Glock 20 21 set is Trijicon’s suppressor and optic height iron sight set for large frame Glock pistols. It fits the Glock 20, 21, 29, 30, 36, 40 and 41, including the S and SF variants. The blades are taller than standard so they clear a suppressor or co witness through a mounted red dot, and every lamp is tritium so they work without batteries.

Why The Trijicon Suppressor Sights Glock 20 21 Set Is Taller Than Standard

Two things put an iron sight out of the shooter’s line: a suppressor body that sits above the slide and blocks the view, and a red dot mounted in a slide cut that raises the aiming point above the factory sights. Taller blades solve both problems with the same part.

Overall front blade height on this set measures four hundred and three thousandths of an inch, with the rear at four hundred and fifty one thousandths. That puts the sight picture high enough to appear inside the window of most pistol red dots rather than below it, which is what makes the Trijicon Suppressor Sights Glock 20 21 set useful as a backup aiming system.

White Front Ring And A Blacked Out Rear

This particular configuration pairs a white painted ring around the front tritium lamp with a black painted rear. That combination is deliberate. In daylight the eye is pulled to the single white circle up front and finds nothing competing for attention at the rear, which is how a front sight focus is supposed to work.

Three dot sets with white rings front and rear are faster for some shooters and slower for others, because the rear dots can draw the eye off the front blade. If you have ever caught yourself staring at the rear sight under pressure, the blacked out rear on the Trijicon Suppressor Sights Glock 20 21 set is the fix.

Tritium That Works Without Batteries

Both the front and rear lamps on this set glow green. Tritium needs no batteries, no charging and no light source to prime it, which is the entire argument for it over a painted or photoluminescent sight. It simply works at two in the morning in a dark hallway with no warning.

Trijicon houses each lamp in an aluminum cylinder, cushions it in silicone rubber, and caps it with a sapphire jewel. The jewel spreads the light evenly and protects the lamp from solvents and punctures during cleaning. That construction is why the Trijicon Suppressor Sights Glock 20 21 set survives being scrubbed with bore solvent for a decade.

Notch Width, Blade Width And What That Means At Speed

The front blade measures one hundred and forty four thousandths wide against a rear notch of one hundred and fifty thousandths. That leaves only six thousandths of total light on either side of the front sight, which is a tight sight picture by modern standards.

A tight notch is precise and slower to find. A wide notch is fast and forgiving but gives up precision at distance. The Trijicon Suppressor Sights Glock 20 21 set sits on the precise end of that scale, which suits a large frame pistol that is often shot deliberately rather than a compact carry gun drawn at conversational range.

• Square rear notch measuring 0.15 in. across

Installation And Fit

Glock sights are not a hand tool job. The rear sight is a tight dovetail that wants a proper sight pusher, and the front is a hex nut torqued from inside the slide with thread locker. If you do not own the tools, have a gunsmith do it. A bent blade or a scarred slide costs more than the labor.

Confirm your model is on the fit list before ordering. The Trijicon Suppressor Sights Glock 20 21 set covers large frame pistols only. Standard frame guns such as the 17, 19, 45 and 19X take a different part number, and a set that physically fits the dovetail but was cut for another frame size will not regulate correctly.

Who The Trijicon Suppressor Sights Glock 20 21 Set Is Built For

Anyone running a suppressor on a ten millimetre or forty five calibre Glock needs taller irons to see over the can. Anyone mounting a red dot on a large frame Glock wants irons that appear in the window rather than below it, so that a dead battery or a fogged lens does not leave the pistol without a usable aiming reference.

Home defence and duty users get the same benefit without a suppressor or an optic. Taller sights are simply easier to pick up quickly, and tritium means the Trijicon Suppressor Sights Glock 20 21 set is as usable in a dark house as it is on a lit range.
