Ade Advanced Optics Red Dot Adapter/Mount for Sig P320 M17 / M18 to Mount Vortex Venom/Viper Red Dot Sight – Also Fits with Burris Fastfire, Docter Footprint

It fits my m18 and vortex venom rds perfectly with no issues. No filing, however was a mm to small to fill entire optic footprint on slide so if that will be an issue for you…. I mean, it’s an Amazon product do you really expect tactical perfection? If you want high quality, just get the rds designed for your slide or get it custom cut. But it held together and my sight is zeroed at 15 yards no issue. Don’t forget the blue loctite!

Install my Vortex Viper onto my Sig 320 Legion X5 noting that it fits into the slide cut out loosely but thinking whatever it has screws to index it and hold it in place. Except the threads in one of the holds broke part way into the hole so now I have to find a long screw to try grab onto the threads that are left. All this after just two magazines. Waited well after the return window to try it…

I don't know why others having to file anything to fit the M18, tight fit but dropped right on. Using the vortex venom rds no problems found.

It fit mine, no filing is required as others stated. My factory Venom screws were a little long and bottoming out, the ones in the kit that are tapered tightened up without bottoming out.

Plate fit optic as advertised. Plae would not fit on P320 M18. I had to file a side in order for full and correct mounting. ADE has good products but this one needs a little more QA.

Fit, form and functionality were as expected. All hardware was included and fit perfectly on the slide cut out on the Sig P320 M18

Both this for my sig p320 and was not worth the money. It was easy to install but the functionality its the bane of this products existence. I bought it to my mount a Vortex venom sights, but no matter how much locktite I use or if I torque to screws to spec it can never hold a zero and always seems to make the sights screws to loosen. I only get to shoot 50 rounds and the sight starts to wiggle.

The plate fits the firearm perfectly! it was installing the Red Dot that gave me issues. There are four little alignment pins that come with the plate. none of the pins will fit into the wholes in the plate! They are two different sizes. Expressing this to the customer support, I was sent two installation videos and told what the pins were for... really. I just said the pins don't fit?!?So I picked up and installed an EGW plate (1.5X money) with zero problems in less than 15 minutes. Off it goes into the "play with it later box" and I to the range to zero in the customers firearm...
