The AmeriGlo Red Fiber .115 Front/Black Rear sight set is purpose-built for Glock's slim-frame concealed carry lineup—the 42, 43, 43X, and 48. If you carry a compact Glock and want sights that balance speed and precision without unnecessary bulk, this is the pairing that works. The red fiber optic front sight catches light and your eye quickly, while the black rear keeps the sight picture clean and uncluttered. Both are case hardened for durability in a carry gun that might see holster rubs and daily wear.
What makes these sights stand out for everyday carry is their geometry. The front blade at .115" wide is sized for fast target acquisition—not so wide that it clutters your sight picture, not so thin that it's fussy to use. The rear notch is square and properly proportioned to work with that front blade, giving you a consistent sight picture from first shot to follow-ups. Heights are optimized so you get reliable co-witness or a natural sight plane whether your slide is MOS-milled or standard.
AmeriGlo's case-hardened finish stands up to the wear that comes with a carry gun. These aren't target-range queen sights; they're made to live on a pistol that gets used. Installation requires basic armorer skills or a gunsmith, but once on, they'll stay put. If you're running suppressed or plan to add a red dot to an MOS slide later, these sights won't get in the way.

Frequently Asked Questions
Do these sights fit my Glock 43X or 48?
Yes. This set is compatible with Glock 42, 43, 43X, and 48 slides. They also work with MOS-milled versions of these guns, so if you plan to run a red dot on an MOS slide, these iron sights will co-witness or sit lower depending on your dot platform.
What's the difference between the red fiber front and black rear?
The red fiber front sight uses a fiber optic rod to gather ambient light, making the front sight stand out in your field of view for faster target pickup. The black rear is a traditional design with no fiber; it stays unlit and neutral so your eye focuses on the glowing front sight as your aiming reference. This contrast is proven for speed and accuracy in tactical and defensive shooting.
Are these sights good for concealed carry?
Yes. The slim .115" front blade is scaled for compact pistols and fast shooting. The squared rear notch and overall dimensions are built around the ergonomics of guns you carry and draw from concealment daily. The case hardened finish is tough enough to handle holster wear without looking worn out.
Do I need a gunsmith to install these?
Glock sight installation requires disassembling the slide and pressing the old sights out and new ones in. This is doable with proper tools and knowledge, but most shooters have a gunsmith or armorer handle it. Check with a local smith or Glock dealer for installation cost and timing.
