Primary Arms has come out with a couple of new reflex sights. Both of these are from their value priced “Classic” line of optics. The two new red dots are the Classic Mini and Classic Micro. Both have 3 MOA dot sizes and are on common mounting footprints, making it easy to mount on various pistol slides.

I’m putting the Micro and Mini together since they both function the same way. These reflex sights are your common “open” style. The main difference is size, weight, and mounting footprint. But as far as function, they are very similar. To turn them on, just push the brightness up button, marked with a plus sign. For off, just hold down the brightness down button for a few seconds, the one marked with a minus sign. If you forget to turn the sights off, they will automatically turn off after 12 hours of use. If you push a button anytime in that window of time, the sight resets the 12 hours. These two red dots both have 10 brightness settings. From sunny daylight bright down to midnight dark. You really can see and use all 10 of the brightness settings, if that’s what you want. The Mini’s up/down buttons are located on the left side of the reflex sight. The Micro has the up button on the left side and the down button on the right side. This is because the Micro is quite a bit smaller than the Mini.

When it comes to small red dot sights, people seem to want to know about battery life. I would tend to say that this is because everyone hates changing batteries. On the Primary Arms Classic Mini and Micro, the CR2032 battery is located on the bottom of the mounting surface. So battery life is more important because the sight must be taken off to change it. I’m not keen on the bottom mount battery, but since the battery lasts approximately 40,000 hours on brightness setting 5, I’m okay with it.

The 3 MOA dot size is a good option for the Micro and Mini. I like the precision that a 3 MOA dot allows. Yet it isn't too small to see on a handgun. I pick up the dot pretty quick with these reflex sights. Surprisingly, the dot on the squarer window of the Micro is easier for me to pick up, even though it is smaller. Don’t get me wrong, the red dot on the Mini’s more rounded window is still easy for me to pick up, but the window size is also noticeably larger. These reflex sights use fully multi-coated lenses to help make that red dot as bright and clear as can be. You do notice a very, very slight tint to them, but it doesn’t distract from seeing your target or the dot. To sight in the dot, they both have 1 MOA adjustment screws at the back and right side of the sights. They use a small allen wrench to adjust them, but they are not click adjustable.

The Classic series Mini is mainly for standard size pistols. It uses a RMR footprint to mount the red dot to a slide, or possibly a picatinny riser. The width is about 1.2 inches, when measured to the outside of the buttons, so it fits nicely on most compact and full size pistols. I really like how Primary Arms designed this for the RMR footprint, as it is one of the industry standards. So finding a slide or pistol to mount the Mini on is super easy. The Mini also has a decent sized window, at 24x17mm. This window is also slightly curved at the top to give you a better view of the red dot. This larger window also makes it easier to find the dot, so to speak. Being the larger of the two red dots, the Mini still comes in with a weight of 0.97 ounces.

Mini size compared to a penny, Micro is smaller yet

Now onto the Classic series Micro. This is the smaller version mainly for use on sub-compact and micro pistols. It measures 1 inch at the buttons, but is actually a little slimmer in real life. Primary Arms uses the RMSc industry standard footprint for the Micro. Using the RMSc footprint is by far the best choice for this red dot. The window size comes in at 21x15mm. Even though the window isn’t very large, the squarer viewing window is easier for me to pick up. I mounted it on a glockish 43 and it looks right at home. The Micro is pretty much half the weight of its larger brother, coming in at 0.56 ounces. The height profile of the Micro also allowed me to use standard height backup sights. It does cut the sight’s viewing angle off some, but they still can be seen fine. So you may not have to purchase new iron sights with the Micro, a definite plus in my book.

Both the Primary Arms Classic Mini and Micro red dots work great. They both handled recoil fine and I didn’t break them. I would recommend these to anyone looking for a cost effective red dot for range, competition, or just “fun” use. With no way to leave them on continuously, carry use is out for me. Look into the Primary Arms RS-10 if you need something for carry or home defense, as it will always be on. For what they are, the Mini and Micro are both great budget friendly options for a reflex style red dot.
