OuterimpactRed Dot Adapter Mount for Sig Sauer P320-M17/X-5 Legion

Searched around found this one the best because of it’s construction and it can fit multiple sightsWould buy if needed for a different brand

This red dot sight adapter plate is absolutely perfect. Fits so many red dots for the sig Sauer p320 M17. High quality also blends in with the pew pew very well. They have many adapter plates for multiple pew pews so if your thinking about getting a red dot for your pew pew this adapter is the go to plate

Does what it's supposed to, if you install it correctly. I did not and parts went flying. The manufacturer was amazing getting me set up with replacement screws. Seriously, don't forget the Loctite.

I’m on board with this being junk. It’s solid aluminum, that should be enough information. If not, just know that aluminum is soft - so soft that the threads wore out quickly. Right out of the box, I noticed that the right side threads wire kind of lose, so I just snugged it up a bit and added loctite to both threads. Well, steel screws inside of aluminum threads? Yeah, disaster. My red dot sight flew off my gun after just 2 shots. The gunsmith at the range, who I’m cool with, examined everything and concluded that the fault was the mounting plate. The bolts pulled right out of the threads because aluminum just isn’t strong enough to hold them down since it’s only like 2 threads per hole. He called it a POS. There is a company that sells aluminum mounting plates that have stainless steel threaded inserts. I feel that would be more durable. I suggest that this company should consider doing the same . So yeah, it’s garbage.

OUTERIMPACT makes mounting plates that will work with any gun and sight. Or so it seems to me, they had the mounting plate I needed to mount a Holosun 407CO to my SIG P320 X-Compact and that's not easy to find. Plus their customer service is excellent. I wrote an email and got an answer back within hours. Plus they continued to work with me to fully understand and explain how to fix and fit my sight onto their plate sending me detailed instructions. I have to say I am impressed and if you need a mounting plate for your gun/sight just contact them.

It works great looks good I'm very happy

Fits Sig M17 p320, also mounts easily to a holosun red dot. Still testing it out to see how it holds up but seems to be solid after 200ish rounds.

Needed this for my sights on my M18 to adapt the the screw alignment.
