ADE Advanced Optics RD3-009 5 MOA Red Dot Sight with Mounting Plate for Smith & Wesson MP M&P, M&P 2.0, SD9VE, SD40VE Pistols + Additional Standard Picatinny Mount

I have been wanting to try a Red Dot Reflex Sight on one of my M&P pistols without having to take it in to have the slide machined and have it a permanent install if I ended up not liking it. Well this is EXACTLY what I have been looking for and it was very easy to install, adjust and start shooting better with. After a 30 minute install I took the pistol down to my Gun Range and sighted in the variable density Red Dot at 25 yards. I then took it off the rest and shot another 50 rounds at 25 yards and was amazed how well I could keep the shots inside a 4" circle. A purchase well worth every penny. I have since put about 500 rounds through the pistol and it's still holding a great zero.

All is well.

UPDATE 02APR22 - I ended up having to use a UTG adapter plate to mount this to an M&P Shield. The mount worked great, the sight not so much. - I taught a combat pistol fundamentals class over the weekend and decided to test this sight. Things didn't go well. The dot, even at its brightest isn't bright enough during the day. I was in the California desert and as soon as there was full sunlight the dot was washed out. I ended up switching to a G19 with a Holosun in order to keep the class going. - At the conclusion of class I decided to move into a shaded area and give the sight another try. I found that it shut off frequently. Sometimes after a single shot, sometimes after 2 or 3. The sight was mounted with the rubber shock isolation pad and without. The pad didn't seem to make a difference. I WANTED to like this RDS, but sadly it's just not up to par with a reputable brand. First off, having shot iron sights all my life, I bought this to experiment with a pistol optic. It looks good out of the box, but thats about it... There are zero mounting instructions. First, Replacing the rear sight with the threaded dovetail mount is impossible out of the box. The dovetail mount is made of anodized aluminum and is overly tight. It has to be filed to fit. The sight adapter base isn't cut for an exact fit to the slide. To the contrary it seems to have some universal radius cut into the underside. Once the sight is attached and bolted down, the adapter base tilts back to the point that you can't adjust the elevation on the sight low enough to match point of aim with point of impact. On the M&P shield as well as the M&P9, The slide just behind the rear sight dovetail is slightly lower than the rest of the slide. They're not even all the way across like a Glock. The adapter plate isn't made taking this into account, causing this upward cant. There's a rubber damper included thats supposed to be placed between the sight and mount plate. I tried the sight with and without the damper and I still couldn't get the thing sighted in. The screws are dead soft and I could feel the heads starting to strip as I tightened them. The sight itself seems to be OK. It might even work if mounted directly to the slide. But using the adapter, it's completely useless. Sadly I think filing the dovetail adapter has voided all hope of being able to return. So now I guess I'm stuck with it. Maybe I'll mill the slide it accept the sight by itself and see how it works out. Also, don't be fooled by the American flag on the side of the optic. It's manufactured in the People's Republic of China. So, it's no surprise it doesn't fit right.

Pros: Easy install, bright, budget friendly. For the price you can’t get any better. Put it on my SD9VE as a part of my budget build gun. Haven’t been able to get to the range yet; that’ll be the true test on how quickly I can get it to zero and how well it will hold zero. Cons: Took forever to get delivered. May need a shim to to fix the zero (we decide after some range time), instructions weren’t that clear. Definitely will purchase from ADE again

Dot is on the money. Most accurate

Decent red dot, my first complaint is, they loctite the battery cover down so the screws strip super easy trying to get them out, it does mount to the sd9ve you just have to use the longer screws and other base plate they send, it does come packaged very nicely and they do include a battery, I'd rate 5 stars if not for the hassle of the loctite, and the little cover to protect the site seems to constantly turn the red dot on so I dont even use it now.

I ordered this and installed it. I had a little bit of an issue getting it cited. Talk to the company without questions sent me what was needed to rectify my issue which was my own fault. Free of charge then I had an issue with stripping a screw out, which was probably also my own fault again without issue rectified the situation and sent me what I needed. Great customer service fast shipping highly recommend.

Looks great! Thank you!
