Rock Slide USA - RS2

 Rock Slide USA has come on the market with some pretty nice products. Of which is their Glock slides. The slides come in two different versions, with options available for both models. The model I received for review is their RS2, with a RMR cut, in black, for a Glock 17. This was a stripped slide, meaning it had no parts in it.

 When I first opened the box, I was impressed. The machining was beautiful. As was the black coating. Rock Slide Cerakotes all of their slides, so this RS2 is black Cerakote. I immediately installed my Glock parts kit. All the parts went in like they should. Since this slide has a cut-out for an RMR, I proceeded to install my Holosun 507 as it uses a RMR mounting platform. I did notice that the 507 moved a tiny bit back and forth on the slide’s studs. The RS2 has studs that the red dot sight goes over and then the sight screws go into the studs. This movement was minor and didn’t cause any problems. The stud option allows for a tight fit without having to have a custom milled slide. So, I tightened down the Holosun. Rock slide also sent me a cover plate. I did put it on just to see how it fit. As expected, it fit and lined up great. They also make this slide with a Vortex Venom cut, for those wanting a less expensive sight.

 Rock Slide did a nice job with the aesthetics also. Being that this is the RS2, it has vents cut out on the front of the slide. The RS1 does not have these. The vents are cut at an angle toward the rear. I also found that these vents are large enough to act as front slide serrations. Speaking of serrations, the ones on the rear are angled and sharp enough to give good grip. The slide is also beveled on top from the ejection port forward. It gives a distinct appearance and makes it not look so Glock like.

 I mounted up the Rock Slide to a Polymer 80 frame. The slide was a nice snug fit without hardly any side to side or up/down play. It is also using a Faxon Firearms barrel which it also mated very nicely too. For the record, I did not install any iron sights on the RS2, but it does have the rear dovetail and front oval hole for standard Glock sights. This slide makes the handgun shoot great! Better than another slide I have used. So Rock Slide’s claim of better performance are spot on.

 Ever since receiving the slide, I have shot this handgun more than any other. The RS2 runs smooth. I have shot it in a Speed Steel match with zero problems. Not counting the other times I have shot it at the range. I am very impressed with the accuracy and functionality of this slide. Plus I think it looks good.

 Please go take a look at Rock Slide USA. This RS2 slide is great. Rock slide also manufactures barrels for these slides. The slides start at $200, with options to basically have a complete slide with sights and an optic! Different color options too. They are also made in the USA with a lifetime warranty.

Top notch company!!! I received my slide within a couple weeks after ordering, it looked and ran great, unfortunately there was a small ridge on the chamber face that I didn’t even notice until I ran some rounds through it. It was just enough to slightly dent the fired case head, I reload my ammo or I probably wouldn’t have worried about it. I gave Rock Slide a call, they said no problem, sent a postage paid return label and I had a replacement slide within two weeks. The slide is flawless, the finish is awesome, it fits the frame great, looks and runs great. I had the venom sight cut which fits absolutely perfect. I couldn’t be happier with my purchase and the great customer service. I highly recommend Rock Slide USA to anyone who is looking for a quality custom slide. Check out the other products they offer too, I picked up a SilencerCo threaded barrel and extra mags for my Glock 17 and the pricing on everything is very reasonable.

Holosun HS507C

 If you have listened to the podcast, you already know that we are fans of the Holosun products. Holosun came out with their micro reflex sight, the HS507c, some time ago. This little reflex sight has some really awesome features. After waiting a while for the green one to come out, I asked if they would send a red one out for review. Yes, I got tired of waiting for the green, which is either available now, or soon will be.

 The HS507c is small. Coming in at 2.65 ounces, it is light also. Dimensions are - 1.8” long, 1.2” wide, and 1.6” tall. The visible window is 0.63”x0.91”. I like the window size, it works well for me. One of my favorite aspects of the 507’s are their “industry standard” mounting platform. Holosun did some homework and decided to use the Trijicon RMR mounting holes and form factor. This means the 507 should work with all RMR cut pistol slides and mounting bases. I used it on two different RMR cut glock slides. The 507 fit both of them just great.

 As opposed to many other micro red dot sights, the 507 has different reticle options. Not only can you choose the 2moa dot, but also a circle dot, or just the ring! The ring is a 32moa circle, and the circle dot adds in the 2moa dot in the center of that ring. I tried out all 3 types of reticles. I liked the ring only reticle for close up shooting, around 5 yards and closer. Of course the circle dot worked well for me from about 5-10 yards. Which leaves the 2moa dot. The dot is what I actually leave the sight set to. Brightness adjustments are on the left side with a “+ or -” button. There are 10 daylight and 2 night vision settings. I found that the dot reticle works best for me, of course your choices might be different. Either way, the Holosun gives you choices that other sight manufacturers don’t.

 The Holosun HS507c is also packed with a “Solar Failsafe”. Yes that means that the 507 can be run off of solar power. On top of the window housing is a solar panel. The panel allows the 507 to run without the need of a battery in all but the very darkest of conditions. This feature also automatically adjusts the diodes brightness. I am not big into auto adjusting sights, but the Holosun’s works well. FYI, I don’t like the auto adjust features because if the sight is in a dark place, and the targets are well lit, the dot will not be bright enough on the target. Having a “Failsafe” for when or if the battery dies is still a great option. Speaking of battery, it uses a CR2032 with up to 100,000 hours of life. Or around 50,000 hours of constant on in the middle brightness setting. It is a good thing that it has long battery life. To change the battery, one has to remove the sight, as the battery is changed through the bottom of the sight. Not my favorite, especially since some of Holosun’s regular sights have a battery tray on the side.

 If you are using the 507 in the battery mode, it has an auto off/shake awake feature. As one can guess, the sight will automatically turn off after a set time time period of no movement. Settings are something like 1,2,4 hours of non-use. There is also a “don’t turn off” feature. The instructions tell you what buttons to press for adjusting this. Along with the auto off comes the shake awake feature. Just as it states, any movement of the sight will wake it up to the last brightness setting. I left the 507 in my safe, facing to where I could see it. It is so sensitive, that just opening the safe would turn it on. So I left it undisturbed in a safe, dark place. When I returned, I could tell the sight was off, when I just touched the sight lightly, it turned on! So it works spectacularly. This feature aids in the extra long battery life.

 This little sight is a beast. The 7075 anodized aluminum housing can take quite a beating. They rate the thing at 5000G’s! I even ran the 507 loose, yes I didn’t loctite the screws at first. If you want to use the 507 on something else, it does come with a picatinny rail mount.

 I may not have as many rounds through the sight as I’d like. But so far, the 507 has done everything I wanted it to do, even more. The dot or circle is pretty clear. A lot better than many red dots, but not as sharp as a few. Some notable firearms people have used the 507 way more than me. Guess what, they have held up for them. I’d say the 507 is good to go, especially since I have used other products from Holosun.

 All in all, I am super happy with the HS507c. Holosun turns out a nice product. It has various reticle, auto off/on functioning, solar use, and uses a RMR mounting pattern. So if you are looking into something like this sight, check out Holosun. Holosun keeps impressing me with their products.

Better Than The Rest... HANDS... DOWN!

I have to say, this beats out the RMR on EVERY front. I gave the RMR a try and it failed miserably to impress me, especially for almost $600.

The HS507C is rugged and has withstood my 1,000 round test on my 226 Legion. It’s dead accurate with the 2MOA dot and the CQB Circle it fantastic for that speedy target acquisition. Holds zero perfectly as I didn’t have to adjust it at all since I sighted it in with the first mag.

The clarity of the glass and lack of severe parallax (unlike the RMR) is unparalleled in such a rugged micro red dot. The ability to change reticles puts it a head above the rest and the battery life is second to none! 10 + YEARS! I’ve used them all, The Delta Point, Burris FastFire, Doctor, RMR, Vortex Venom, etc.

The auto adjust brightness works well and on a sunny Texas day that dot it bright and very crisp. The RMR is splotchy and oblong.

For only $300 you are getting a VERY Feature-Rich product that has a lifetime warranty to back it and it worked so well I bought a second one.

Definitely worth the money and don’t get me wrong, I waited 3 months for the first one, it was agony and I wasn’t expecting to wait any longer than 2 weeks for the backorder. But honestly it was DEFINITELY worth the wait.

5 stars all day long. And I have worked with Holosun before and if you have a problem, they will fix it and have it back to you up and running within a week.

Let’s face it, even Trijicon and Leupold manufacture a lemon every once in a while. It’s the luck of the draw when it comes to mass produced items.
