The HE507K-GR X2 improves on previous the version by adding Lock Mode which was first introduced in our 2018 LEM pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes.Additional features include Holosuns Green Super LED with up to 50k hour battery life, Multi-Reticle System, and Shake Awake. The durable housing is made from 7075 Aluminum, uses Holosuns K footprint, and houses the 1620 battery in a side-mounted tray for easy replacement when needed. The HS507K X2 is a direct for P365X/XL, and requires an adapter plate for slides with a four-boss interface

BAIT and SWITCH.
The Optic Sight was advertised as as GREEN DOT thats what the GR Means, That being said I bid on it id then got a less expensive model Still a Good Sight But it was Boxed in The More Expensive Box.. I could hav spent a little more for a NEW one with a Warranty! They have the correct item, but told me they did NOT! Well I found it on the store page at the SAME price That I could get it from the Maker.. All TRUST Is Lost with this outfit... I did not want RED!!! I may have saved a couple of bucks, But that's not the POINT!!

Great Micro RDS choice
The 507K is a great optic for it's size. I have 2, one red, and one green. I prefer the green. Love the options of 3 reticles. The overall size is nice compact and works well on my 365XL, 1911, and have my P320 with out hanging over the sides of the slide. Though the 507K does have backup iron sights built in to the sight body they are minimal and are not extremely effective. I would like to see of them taller and have contrast dots to actually be effective iron sights. Though this did not effect my overall rating.

Durable and good build quality
Good build quality. Fit perfectly and looks custom made for Mossberg 590S. Controls are very intuitive and easy to adjust. Holds zero, even on a 12 gauge with larger 2 3/4" shells. Would recommend to anyone with RMSc firearm fingerprint.

Great Size for Single Stacks!
Whoa, I really like this thing! It fits VERY nicely on Single Stack size Semi-Autos, like Glock 42 & 43s or the Beretta 80x. And the green dot is the "cats meow". I don't expect to go back to a red dot any time soon! Nicely done Holosun!! I will reserve durability judgement until I've had it a bit longer.

The one
This red dot is a great accessory for your pistol! improved my rapid shooting by 50% and as far as range shooting just zero it in and you'll be very happy. It's almost like your cheating I'll be putting them on all my pistols.
