Got this for my 43x and works perfectly. Had to get an adapter plate but that was expected. It mounts study and comes with multiple differ length screws depending on what you need. It is very durable and have not had an issue with it so far. The red dot is clean and is easy to find. The brightness is also adjustable.

Holosun 407K X2. Before I 'review', it should be said that this is my first red dot on a handgun, and I fell in love with the concept, sooo... Mounted it on a new Equalizer, here's my info and thoughts; 1) Yes, it fits perfectly on the Equalizer with no plate or mill work needed on the slide. 2) No, it DOES NOT come with the correct screws to mount the site. This is bogus on the part of Holosun and needs to be addressed. Too pricey of a sight to not come with all types of mounting screws. 3) Because of that, you will need two 6-32 black oxide flat head socket screws. You can get these at most local hardware stores for about .40 cents each. I bought the 1/2" long overall length screws because that's all they had, but 9/16 or even 5/8" length would be better. The 1/2" do work though. Make sure you clean the oil off the screws and out of the slide holes before putting the loctite on and putting the screws in though. 4) Yes, it will barely co-witness with the OEM iron sights. It's not perfect by any stretch, as you can only see about 20% of the front sight, but in an emergency situation, the iron sights would be usable and accurate with the 407K mounted. 5) It works/fits very nicely with the IWB holster I bought (crossbreed). Took it to the range today. Wow. I was impressed! The 6MOA is perfect for me, and it only needed a few clicks up and right to be dead on after mounting it. Once sighted in, it held zero flawlessly round after round. I really like that you can change the battery without removing the sight, and the shake awake feature is super-sensitive and works very well. I love being able to stay on target with both eyes open to the surroundings. Despite the missing screws debacle, I would still buy it again. Nice sight.

Perfect. Easy to mount. Used plate no. 4. Check which plate will work for you and order separately. Great value, you won't be disappointed.
