This little 507K was purchased to top off a new firearm that was pre cut to accept the 407K/507K. It fit like a glove and was simple to install. It performs flawlessly like all Holosun optics I've tried. The dot is easy to find and the multi reticle gives me 3 choices. This is daylight bright even in the brightest sun. Other Holosun optics I've had take a lickin and keep on runnin. I could by the BIG name super spendy stuff, but why. Holosun is miles ahead of the competition when it comes to design. For me every Holosun product I've owned has lasted. They're well built and priced well. Of course right after I bought this, I saw it on a great sale for $70 less. That's just my bad luck. Two big thumbs up Holosun and Amazon. Super fast shipping and our Amazon delivery people are the best of the best. Kind, cordial, and always professional. Happy Labor Day 24 to all.

The quality of the sight is perfect. Fits excellent on my 43x. It’s very easy to function and very durable. You will need an adapter plate if you have an MOS cut but it’s so easy to install. Just don’t over torque the screws and or use extra lock tight and it’s gonna never move on you. Very easy to sight in as well. I would highly recommend this sight. ... show more

Nice, small reflex sight. Fit my wife's handgun perfectly and easily installed. It appears to hold zero well, feels durable, and the brand is well respected. So I'm happy with it.

I purchased this Holosun by mistake! Once I received the 507k I realized I needed the 507c (507k for micro to sub compact RMR slides) 507c for full size RMR slides. If I need to purchase this optic again I would! Price was amazing and shipping time fast!

This green dot site was easy to install and functions perfectly on my Sig Sauer P365 X-Macro. Need to get a new pocket holster for it as I need the optic area cut-out. This site lines up during natural stance and draw. The green color of the reticle is one of the easiest wavelengths of light for the human eye to see in most conditions. ... show more

Color: Red 2 MOA Dot & 32 MOA Circle (HS507...
First the bad: The reticle is tilted to one side, it’s not square. With the dot or circle you won’t notice it of course, but with the crosshair-style reticle, you notice it. I’ve read others who have had this issue, I guess it’s within the margin of error so they let it go. It isn’t going to affect shooting to any noticeable degree, but it’s not the way it should be, simply put. Yeah, it’s lower cost than a Trijicon or something, but it’s still high enough price that it should get that right (I have seen and owned cheaper sights, and none of them have had tilted reticles). At times it can lock up and not respond to any input. Happened once to me, wouldn’t change from the dot reticle and wouldn’t turn off. It turns out that Holosun actually has directions on how to fix this, and it’s simple (you hold the buttons or something a certain way, I forget), but if you don’t look it up and see it on their website or a forum, you might be pretty angry about it until you do. Mine responded fine and went back to normal. The good: Well, basically everything else for now (haven’t needed customer service yet, we’ll see). I like the shape, I like the reticle options, I like the brightness and the lens clarity, I like the fit and finish (other than the glaring issue with the tilted reticle), I like how it looks, the weight, etc. Of course price is a large factor here as well. ... show more

Picked this up for my Springfield Mod 2 .45 and needed something that would hold up as it is my CCW pistol. This definitely holds up and I've never had any issues with it. Always hold true no matter how much I've accidentally knocked it or if its been rattled while in the gun safe. Highly recommended, will definitely order another one! ... show more
