The Strike Industries SI Iron Sights are a front and rear set built to replace the factory sights on your Sig Sauer P320 with something that gives you a cleaner, more usable picture on target. These are machined from SUS630 hardened stainless steel, so they hold up to a rough life of carry, holster wear, and range days without complaint. If your OEM sights feel a little flat or hard to pick up in changing light, this set is a straightforward upgrade that won't break the bank.
The real story here is the geometry. The rear sight uses a U-notch shape with a negative angle cut into the back wall, which keeps that surface dark so your eye stays locked on the front post instead of wandering. There's also a line running down the center of the rear that catches light from above and creates a visual guide to help you center up faster. Small steps machined into the rear of both sights knock down glare and reflections coming back at you, which makes a real difference outdoors in bright sun.
The front post comes blank, so you can leave it plain or paint it whatever color reads best for your eyes. A lot of folks run a dab of bright orange or a glow-in-the-dark paint for quicker pickup in low light. On the P320, the front sight sits at 0.167 inches and the rear at 0.169 inches, putting them in an absolute co-witness position if you're running a slide-mounted red dot down the road.
These are designed for Sig P320 slides with a rear dovetail. They're semi-drop-in, which means depending on your exact slide they may need a little light filing to seat just right, since not every aftermarket dovetail is cut the same. The kit comes with everything you need to get them mounted, including the set screw, hex key, and thread locker.
They're made for Sig Sauer P320 slides that have a rear dovetail cut, which covers the standard OEM setup. Keep in mind they're semi-drop-in, so depending on your specific slide you may need to do a little light filing to get a snug fit. Aftermarket dovetails in particular aren't always cut the same, so a proper install matters.
The front post ships blank, which gives you the freedom to paint it whatever color works best for your eyes. Plenty of people go with bright orange or a glow-in-the-dark paint for faster pickup in low light. If you'd rather leave it plain, the machined stainless steel works fine as-is.
Yes. In the standard height, the front sits at 0.167 inches and the rear at 0.169 inches, which places them in an absolute co-witness position with a slide-mounted red dot. That gives you a solid backup aiming reference and helps you find the dot faster when it's mounted.
You get the front sight, the rear sight, a rear sight set screw for the P320 dovetail, a hex key, and a small bottle of blue thread locker. That's everything you need to get them mounted. A common recommendation is to keep the front sight screw torqued to no more than 7 in/lbs.
