I bought this
Trijicon RMRcc for my Sig P365XL, along with the Trijicon adapter plate. I mounted it, but never shot the pistol with the red dot sight, so it's still about as new as you can get. Decided to stay with iron sights for CCW use, and this doesn't fit my new Sig P322, or I'd just keep it. It's a really nice site, and looks to be rugged as all get out!
I got a deal on it, when they had the $100 rebate, so I got it much cheaper than the $700 suggested retail price. I have about $475 into this with the adapter plate. I'll sell it for the same, and I'll cover the shipping to your door.
