Ade Advanced OpticsCompact RD3-009 Red Dot Reflex Sight + Optic Mounting Plate for SW Smith Wesson MP/MP 2.0 Shield SD9VE,SD40VE Pistol and Also a Standard Picatinny Mount – 5 MOA Reflex for Pistols

Works perfectly, fit is great on a sd9 2.0 highly recommend

Comes with adapter plate and riser fits good a little bulky but what can you expect for the cost I like it

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.

For the most part, it was exactly what I expected. The only suggestion is that the instructions could be a little more informative. They were a little vague and did not show a couple of details that would have been helpful.

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.

I bought this sight because it explicitly stated that it would fit my Tisas Zigana PX-9 9 mm pistol. When it arrived, I powered it on and the red dot appeared as expected, and I was able to vary the brightness as the owner's manual stated.I couldn't get the rear iron sight off the pistol, so I took it to my gunsmith and left it with him. He called the next day and said it had been difficult for him to get the iron sight off, but he was able to. The problem was the two part mounting plate didn't fit properly to mount the sight on. The dovetail portion of the mount had significant play, and the main part of the plate didn't seat properly on the gun's slide. There was no way he could secure the mount and the sight properly to the slide.Returned it today, and after a three-way conference call between myself, my gunsmith, and SDS Imports (it's a Turkish gun) to make sure what I was planning to order would work, I ordered a Holosun 407c-x2 and a one piece RMR mount.

ADE Optical provided great customer service when I asked them questions about the red dot I purchased. Their replies were prompt, although they mostly re-stated their FAQs. I have not gotten to the range to confirm sighting, but if my laser bore sighter is accurate then this red dot will be accurate as well. I did request the 1 degree plate shim, but the screws provided to fasten the optic to my S&W M&P are barely long enough to use it. I will probably buy longer screws even though M3.5 screws are very hard to find.

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.
