Sig P320 X5 Legion
This product fixed the mounting issues I was having with my RMR sight. Now my RDO is fitted, snug and holding zero. It seems that the stock mounting holes in the Legion slide is too short and the thread size/pitch didn’t match the screws that came with my sight. No mater what I tried, I just couldn’t get the sight mounted securely. At least not until I got this adapter plate. This adapter plate is over engineered and is attached using the larger screw holes available in the slide. The adapter plate provides pegs for the RDO to align with as well as its own screws to attach the RDO to the plate. All in all a very well designed product for a very specific application to solve a unique issue of mounting any RMR RDO to the P320 X5 Legion. This is a must have and worth every penny for the amount of time and frustration it will save you. ... show more

Absolutely PERFECT!!!
The plate fit my P320 perfectly to allow my optic to mount to it. Very low profile but still sturdy enough to keep the optic in place through over 1000 rounds.

Bad craftsmanship
The holes do not aline to the red dot. I didn't try to install in the return time as had a hard time finding the correct screws to my Sig X5 Legion. Waste of money 💰 and trying to get my money back or a plate that actually has the correct holes to screw in my red dot.

Works great
The plate itself is perfect fit great and mounted right up the only issue I had was the threaded pin posts one of them snapped as soon as I torqued it , thankfully there was a spare other than that 10/10.

Works great! Little spendy, but quality is excellent.
Paired with a SwampFox Liberty (with the Ironsides Shield). The little 'legs' for the plate threw me off a little, but a quick call to C+H Precision's customer service and my confidence was restored. I'm using the OEM front site, and the red dot disappears perfectly when the front and rear iron sights are aligned. I'm sure if the protective Shield on the Liberty was not there, the red-dot would align perfectly. But for my application and MacGyver abilities, it does the job. Just don't tell my wife how much I actually paid for it, and I'll be fine. 10/10 would recommend. ... show more

Perfect for x-carry
Added this to my p320 x-carry legion. Great to have a red dot without giving up back up irons. I read that some people are having trouble with it holding up to recoil, but mine has been fine so far. Be sure to follow their instructions as a buddy of mine and I both messed up the lugs that the screws go into by using the longer screws. I will return and update review if it breaks due to recoil. ... show more

High hopes but no dice.
Just a heads up, does NOT WORK with a Commemorative P320. Looks good. Make sure you know what you are buying.

Exactly what I needed!
Loved it . Just make sure you have the exact plate adapter for your make and model it needs to be the rite footprint. Make sure you watch YouTube before buying or installing as you will need locktight and a torque Allen key wrench that is long enough. Trust me you’re going to need it.
