Brownells 1L Tall Black Sight Set Serrated .220''F/.295''R For Glock

The Brownells 1L Tall Black Sight Set is a serrated iron sight solution built for Glock pistols running compact red dot optics. The 1L height (.220" front / .295" rear) is engineered specifically for slide-mounted reflex sights like the Holosun 507K/407K, EPS Carry, or Vortex Defender. Whether you're running a Glock 43X/48 MOS or adapting a standard Glock frame with an aftermarket slide, these sights bridge the gap between your iron backup and your mounted optic for cowitness alignment.

Both the front and rear sights are serrated and finished in matte black to kill glare under bright conditions—a practical detail when you need your sights to stay visible but not distracting. The rear sight features a U-notch cut that lets you index the front sight post quickly and intuitively, making it easy to get a solid sight picture without fumbling. Brownells engineered these sights for their own slides, but they'll drop right into any standard Glock with conventional sight cuts.

The 1L variant uses a slimmer rear sight width that still fits the standard Glock 17/19 rear dovetail cut. If you're pairing this with a Holosun EPS on a standard Glock MOS, you'll achieve a lower 1/3 cowitness—a sweet spot for many shooters who want their irons visible but not dominant in the sight picture. These are honest backup sights for a modern setup, not a gimmick or compromise.

Frequently Asked Questions

Will the 1L sight set fit my Glock?

The 1L is designed to work with any standard Glock pistol that has conventional sight cuts. It is optimized for Glock 43X/48 frames paired with compact red dot optics like the Holosun 507K/407K, EPS Carry, or Vortex Defender. The slimmer rear sight width fits the standard Glock 17/19 rear dovetail cut.

What red dots are these sights designed to cowitness with?

The 1L height is matched to compact optics including the Holosun 507K, Holosun 407K, EPS Carry, and Vortex Defender. When mounted on a standard Glock MOS, pairing the 1L sights with a Holosun EPS will produce a lower 1/3 cowitness.

What's the difference between the 1L, XL, and 3XL versions?

The three versions offer different heights to accommodate different slide-mounted red dot sizes. The 1L (.220" front / .295" rear) is for compact dots on small-frame pistols. The XL and 3XL are taller for medium and larger optics on full-size and compact Glocks.

Are these sights serrated on both front and rear?

Yes. Both the front and rear sights are serrated and finished in matte black to reduce glare and aid in rapid sight acquisition.
