The XS F8 set takes a smart approach to a notch-and-post sight picture. Instead of the classic three-dot layout, XS stacks one dot over the other to create a figure-8 when your sights are aligned. That means no more second-guessing which dot is front and which is rear when the pressure is on. Your eye locks onto that big orange front ring, drops it into the wide rear U-notch, and you're lined up.
The front post is where this set earns its keep. XS builds it around a 0.160-inch wide blade wrapped in a photoluminescent orange ring, with a green tritium vial in the center. The orange grabs your eye in daylight and dusk, the tritium keeps it glowing in the dark, and the ring even charges off a flashlight or bright light to give you a little extra glow when you need it. Folks whose eyes have started to slow down on standard sights tend to notice the difference right away.
The rear on the F8 is all business. It runs a single tritium dot below a wide notch, with the gap opened up on purpose to let light spill around the front post so you find it faster. The base of the notch is rounded to pull your focus to the top edges for clean alignment, and the rear face overhangs slightly to knock down glare in bright sun. There's also a flat ledge on the back for one-handed slide work against a belt or boot heel.
These fit a wide spread of pistols including the SIG P320, P225, P226, P228, P229, and P365, plus the Springfield XD, XD(M), XD-S, XD-E, and the FN 509. Each sight is CNC machined from solid steel bar stock with a matte black finish, so they hold up to real range and carry use. Install goes quick by hand or with a sight pusher. One thing worth noting: the F8 front rides taller than most factory sights, so double-check your holster fit before you head out.
The F8 uses a dot-over-dot design instead of the usual three dots across. When your sights are aligned, the front tritium dot sits directly on top of the rear dot to form a figure 8. It's a foolproof setup that keeps you from mixing up front and rear dots, and it draws your focus straight to that big front post.
Yes. This SI-F012P-5 set is cut for the SIG P320, P225, P226, P228, P229, and P365, along with the Springfield XD, XD(M), XD-S, XD-E, and the FN 509. It does not fit X or XL series pistols where the rear sight is part of the optics plate, so check your specific model first.
You can install them by hand or with a sight pusher tool, and many people use a brass punch and hammer with the slide supported. A sight pusher makes it a lot cleaner and is worth having if you swap sights often. If you're not comfortable with the job, a gunsmith can knock it out in a few minutes.
Yes, the F8 front rides taller than most standard factory sights, which gives you a more natural sight alignment and lets them work as backup irons behind certain optics. The tradeoff is that some holsters cut close to the slide may need to be swapped, so confirm your holster clears the taller front post.
