A red dot sight is a kind of optic designed for close to mid-range shooting confrontations. This red dot produces a reticle, an illuminated red dot, which you can use to sight your target. A good red dot sight may make a huge difference in target acquisition speed, shooting accuracy, and precision while using a pistol. Whether you want to target, shoot, compete, or hunt, here is the place to be.
The Differences Between Shield RMSC and Holosun 407k:
The red dots on firearms are fantastic. They allow you to fire faster and more precisely since you merely place a dot on your target rather than lining up sights.
Furthermore, concealed carry pistols are becoming increasingly compact, but luckily for us, some optics firms are stepping up and developing red dot sights which will fit on these small guns.

Detailed comparison between Shield RMSC and Holosun 407k:
Build & Durability:
Shield RMSC: The Shield RMSC was among the first compact reflex sights to hit the market, and the acronym RMSC stood for “Reflex MINI Sight Compact.”
I believe it’s a fairly difficult little sight. It boasts a high-quality aluminum sight housing with an anodized coating to preserve it from the weather.
Furthermore, the windage and altitude turrets on the RMSC are recessed within the sight housing, ensuring they are never mistakenly bumped or snapped off.
In addition, the RMSC is waterproof to be used in the rain or snow. And it was built from the beginning as a pistol optic. So it is shockproof and can be installed on the slide of a handgun.
Holosun 407k: The Holosun 407k is likewise a tough little reflex sight. The sight housing of the 407k, for example, is likewise made of 7075 T6 aluminum. As a result, it’s quite difficult.
It also features an anodized coating to assist it in resisting the weather, and the windage and altitude turrets are recessed inside the sight housing. As a result, they can never be severed.
Finally, the 407k is waterproof in up to 1 meter of water and will perform admirably in rainy and damp weather.
Battery Life:
Shield RMSC: The Shield RMSC is powered by a single CR2032 battery that will last for 2 to 3 years. Again, I appreciate exceptionally extended battery life on my optics since it reduces the likelihood that your optic may die on you in an emergency.
Changing the battery on the RMSC requires you to remove the optic from your pistol. Because the battery is placed at the bottom of the optic, this is a tremendous hassle since you’ll have to re-mount the sight and then take your pistol to the range to re-zero the optic.
Furthermore, the RMSC does not feature any manual brightness changes. In my opinion, all of the modifications are automated, which is a drawback.
Under typical lighting situations, auto-adjusting the brightness settings isn’t a big deal. However, under rare circumstances, like the shooter being in a darkened house and shooting into the strong sun or attempting to use the dot at nighttime with a flashlight, the auto readjustment might cause issues.
I would have appreciated it if the RMSC offered both the auto adjustment capability and a manual way to alter your brightness settings.
Holosun 407k: The battery life and brightness characteristics of the Holosun 407k are identical to those on the 507k. It also uses a single CR1632 battery, which can power the sight for 50,000 hours.
It also features a side-loading battery tray, which allows you to change your battery (when the time comes) without removing your optic from your gun’s slide.
It also features the Awake Shake feature, which automatically turns your sight off and on when the optic detects motion.
The 407k also features ten daytime brightness levels, the brightest of which is quite bright, and two-night vision settings with NV equipment.
Features and Characteristics:
Shield RMSC: The lens on the Shield RMSC is likewise exceptionally clear. It doesn’t have the unpleasant blue tinge that some red dots have.
Overall, you can see clearly through the optic and get a crisp visual image. When it comes to the reticle on the RMSC, you have two options when you pick up the sight. There are two versions of the RMSC available: one with a fixed 4 MOA dot and one with a fixed 8 MOA dot.
I like smaller MOA dots on my red dot sights because, as previously said, they are still quite fast for your eye to pick up and provide better precision.
So, out of the two options provided by Shield, I like the 4 MOA dot, and I believe the 8 MOA is a little too large for how I like to fire.
That being said, many excellent shooters prefer a 6 MOA or an 8 MOA dot. If you’re attempting to determine which reticle size is best for you, it boils down to personal choice.
Holosun 407k: The Holosun 407k also features an extremely clear lens, providing a great sight image.
But when we start talking about the reticle, things start to change. The reticle on the 407k is a fixed 6 MOA dot.
In terms of precision while pointing and rapidity when picking up the dot, I believe the 6 MOA dot reticle is a reasonable compromise.
I would want it to be somewhat smaller, maybe a 4 MOA dot, but many people enjoy it at 6 MOA. And, since 4 MOA will mount this optic on a single layer concealed carry gun, 6 MOA is an ideal size since, if you ever need to use your weapon in self-defense, the firing distance will most likely be extremely near. Overall, I believe the 6 MOA dot is a nice reticle, but it is the only option for the 407k.
Size Comparison:
The Shield RMSC is a very small micro reflex sight with minor changes in size. The Shield RMSC stands at 0.9 inches in height. The width is 0.9 inches wide, while the height is 1.7 inches tall. And the Shield RMSC is only 0.57 ounces in weight.
The height of the Holosun 407k is 0.95 inches, the width is 0.98 inches, and the length is 1.60 inches. In addition, the Holosun 407k weighs only 1 ounce. So, in addition to being extremely tiny, it is also quite light.
Final Verdict:
All these sights are waterproof and shock-resistant. They get a sight housing constructed of high-grade aluminum in the Endurance And Toughness area.
However, because the 407k’s sight housing is significantly thicker than the RMSC’s, the 407k was declared the winner.
Both sights in the Optic Clarity And Reticle group feature a transparent lens which allows you to receive a very crisp sight image.
The 407k, on the other hand, includes the Multiple Reticle System, which provides three reticles in one sight, such as the Circle Dot Reticle.
Furthermore, the RMSC is restricted to either a fixed 4 MOA dot or a fixed 8 MOA dot. So the 407k came out on top here.
Both of these sights are quite compact, and their dimensions are very close in the Size Comparison, but because the RMSC was slightly lighter, I gave it a minor victory in this area.
Both sights have an extremely long battery life, which is wonderful. However, the 407k features a side-loaded battery tray, adjustable brightness changes, the Shake Awakening, and the Locked Mode. As a result, it was declared the winner.
So, which of these attractions do I prefer? The Holosun 407k is my favorite.
