A side-mounted illumination button is embedded in the polymer housing to prevent accidental adjustments. SIG SAUER's updated footprint ensures industry-standard optics compatibility, with steel recoil pins preventing lateral shift.

    • Well done!
Color: Black Housing Size: 6 MOA Red Dot (SOR02160)
This is great site for the price. I use on my Sig P365 that I use for a CCW. I purchased this and the Elite at the same time and did side by side comparisons. This site won by a lot! Easy to install, perfect fit, 6 MOA, easy to adjust, and much sturdier then than the Elite. The battery replacement is on the side which is very convenient. The Elite has it underneath so you have to take it off to replace. If you are comparing go with this model and version 100%. ... show more

    • Product unusable...
Color: Black Housing Size: 6 MOA Red Dot (SOR02160)
product received. the set screw holding the batter tray was torqued so tight that it stripped the provided star drive wrench. I used one of my star drive wrenches and it stripped it too. product is useless. Amazon sent me to the seller to resolve the issue, the seller claimed it was not their problem. Went back to Amazon and they're finally letting me return it for a full refund. i like Sig products, very disappointed in this experience. ... show more

    • Best affordable pistol sight

I will never spend more money on a sight again. For the money, this sight is awesome. Perfect fit on my full size glocks. Awesome sight! You're crazy to get anything else.

    • Looks great, works decent for the price. But there are better options out there.
Color: Black Housing Size: 3 MOA Red Dot (SOR02130)
I do like this optic and I am confidently running it on my ccw. But I wouldn't recommend it unless you're a huge fan of the aesthetics or the price. There are better overall options out there. PROs: Looks great on the P365X Macro Comp. Relatively cheap. Install is easy. Easy to use. It has its own version of shake-awake. Has a battery tray not requiring removal of the optic and re-zeroing when swapping in a new battery. Clear, wide window. Dot gets significantly bright. CONS: The provided bit used for adjusting the windage and elevation is unique to this optic and this optic only. So if you go to the range without it and the dot seems off, either deal or go back home to get it. Needs re-zeroing after 300-400 round range day. Even with a boresighter at home, this shouldn't be something one needs to do regular maintenance on. For the Sig P365, no co-witness. May not be the case for all sub compact pistols. This looks great on my build, and I do have an at-home boresight and laser cartridges for dry fire for monitoring my zero. ... show more

    • Too many modifications to be worth it.
Color: Black Housing Size: Circle Dot (SOR02100)
Great sight.. IF I can get it attached. Now I have to be a Gunsmith. The screws that came with it did not fit the Gun. P365SAS. The screws that came out of the gun, were 2.5 mm. The screws that came with the sight were, 3 and 4mm. Neither were long enough to be effective even if they were the right size. So.. I have to drill and tap for 3 mm because the top of the sight screw holes are too big for a tapered 2.5 mm screw. And I have to buy a tap,(M3X.05 mm bottom Tap) a 2.5 mm Drill Bit. And Screws that are approximately 15 mm long. If I knew this is what I would be going through, I WOULD NOT DO IT AGAIN. ... show more
