Holosun 507C X2 Review: By A Scout Platoon Sergeant

The Holosun 507C X2 has been successfully competing against commanding brands. It can really increase your accuracy and provide faster target acquisition.

FYI, prices and ratings are accurate as of time of writing.

Hi, shooters. Today I’m reviewing the Holosun 507C. To cut to the chase, you can pay a large stack of dollars for the Trijicon RMR. If you have that large stack of dollars, good for you. For the rest of us, the Holosun 507C is going to do the same job for much less. Of course, you can also get yourself a red dot for half the price of the 507C, but remember: it will weigh half as much as well. You can check out Gary Anderson’s budget red dots review. It’s a very insightful, hands-on guide. And for a reflex red dot designed for longer barrels, check out my Holosun 510C review. Now let’s move on to my hands-on testing of the Holosun 507C.

Holosun 507C X2 - RMR Footprint Red Dot

HIGHLIGHT:

When the battery fails, the solar failsafe on the top of the sight will recharge and operate the red dot.

VALUE:

Once upon a short time ago, an RDS was cost-prohibitive. In other words, everyday people did not have them on a handgun. When I bought the Holosun 507C, I figured, what the heck? It's cheap enough to see if it's worth the money. After testing it extensively, I think there is no need to lay out the cash for something like the RMR when this little Holosun will do the job and save many pennies for ammo. It also includes the necessary Torx screws for installation.

MOUNT SETUP:

I love this little RDS. It's very compact and leaves the "footprint" of the gun small. I carry a Glock 36 in .45 ACP, for those that don't speak the Glock numbering system. I had to use a Glock Rear Sight Mount; it's an RDS mount that uses the stock dovetail when the gun is not cut for an optic. My adapter is made by Strike Industries and screws into the top of my Glock. The screws don't cut into the metal of the slide; they create a very snug pressure with the dovetail notch fit. I had to remove the original Glock backplate and install the one with the adapter. It was easy money. This new backplate is part of the mounting, and now the Holosun 507C is rock solid.

RETICLE OPTIONS:

I am here to tell everyone I love this Holosun! I can have one of three reticles with just the touch of a button. I can go from Dot to Dot-and-Circle or just the circle, depending on my eyeballs, the available light, and what I shoot.

AUTO BRIGHTNESS:

One of the best features is the Auto Brightness function. In sunlight, it turns itself up. In the dimmer settings, it adjusts downward - like magic.

SHAKE AWAKE:

I talked about the Shake Awake technology feature, which is very handy and makes using the red dot foolproof. It will turn off at ten minutes as it comes from the factory. I can set it to shut off at an hour or twelve hours or stay on until the battery goes dead. Once I set it, it stays that way until I change it.

BATTERY:

The battery access is on the right side of the optic and is easily accessible anytime. The instructions claim a battery life of 10,000 hours when using the dot-and-circle reticle and 50,000 hours with just the dot, which makes sense as the single dot requires less power. As much as I like to write the most helpful reviews possible, I am not going to turn on the light and check it to see if the 10,000-hour claim is correct.

SIGHT PICTURE:

As a guy who grew up on iron sights and was a true believer that iron sights were the only option, age and old eyeballs are helping me overcome this bias. After getting used to it, the red dot is easy to pick up and makes a great sight picture, even at a distance.

DESIGN CONCERNS:

My first concern is the lack of drainage around the optic window. If the gun is carried as a side arm, and I am in the rain, the glass will hold water until it is drawn, and the rain can run out of the optic. I think the design should have taken that into consideration. My second concern is the auto-light reaction sensor being mounted on the top (it's the same as the solar failsafe). Outside, or going from inside to outside, it is excellent and reacts quickly. With that said, if I use my pistol-mounted flashlight in a dark area, the lighting sensor will not adjust to the focused bright light, and the dim dot will be washed out. What I did to fix this issue and train for this issue is to use my finger to hold the plus button for three seconds. I switch the sight to manual mode and adjust the reticle to fit the situation. No need to worry about constantly resetting and fooling around with the optic. The Holosun 507C will revert back to the setting I had initially.

FINAL TAKEAWAY:

The Holosun 507C is built with high-quality materials and excellent craftsmanship. It's easy to replace the battery. It has Shake Awake technology, 50,000-hour battery life, and twelve brightness settings. And the multiple reticles are fantastic for making the tool fit the shooter and not the other way around. Who wouldn't appreciate that?
