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%.

I dont think I've ever given a 1 star review but here we are. Order this red dot and it arrived quickly. Packaged well and appeared to be very well made. I pulled the plate off my pistol and used the provided bolts to mount the sight to my slide and torqued to spec. Looked awesome! Then I went to install the battery. It's a side mounted tray thats secured by a single bolt. That bolt uses a T5 bit to remove. Sig included the needed allen style key but I broke the end trying to get the bolt out. Dang. Went and grabbed my own torx kit and then used my T5 in a driver that twisted in half just as the first one. I broke a total of SEVEN T5 bits and a gunsmith almost broke his. I sent this back and promptly email Sigs customer service telling them about my experience. Weeks later I got a reply and a return shipping confirmation. Im glad I ordered one of these to try before I pulled the trigger (see what I did there?) On 3 of then.

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.

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.

not bad. easy to attach. fits direct to most sig pistols. I have the x macro and it mounts direct and includes the screws. the factory sites are too short to co-witness, but you can get taller sights if that is a concern. good price and well made. the device seems durable and the sights are very clear. you can still see the red dot even with a mounted light as well. it is adjustable so you can make it very accurate and it looks very good on the gun

This worked great as an attachment to my straw, to nail the hole in my Capri Sun.
