The MicroReflex red dot for the LCP MAX seems pretty terrible.
As both a red dot enjoyer and a fan of micro pistols I thought this package would be a great upgrade over a stock LCP MAX.
I finally found one in person to handle and while I didn't get to shoot with it, I was more interested in the optic than the pistol. This may be the first time I've ever found an optic to seem inherently worse than iron sights. The window is tremendously small, which was an intended feature to make it mate as slickly as possible on the gun. Normally I don't think window size is variable to care much about, but in this case it is so small that finding the dot in the window essentially requires lining up using the irons before the dot even comes into view. I have a habit of lining up irons with pistol dots but even so I usually at least see the dot in the window before I'm perfectly lined up. On this optic once the dot is in view it is a massive 15MOA red smear. It is not a dot and 15MOA donut, it is a solid gigantic red circle.
The dot is fiber optically illuminated, which seems to me that in the exact situation when you'd want it to be the brightest it will be the dimmest.
This is a very awkward aiming setup. While LCP MAX guns aren't exactly intended as target shooters and the statistical self defense use doesn't even need sights, having the ability to reach out further with faster accuracy is always a good thing, but in this case if I was trying to stretch the reach on an LCP MAX I'd pass on this red dot and keep the irons.
I have the same problem with any small red dot sight. The window is just too small, it takes me forever to find the dot when drawing quickly or under pressure. Any red dot that's big enough to be useful is also too bulky for carrying. The only red dot I use now is on my nightstand gun that doesn't ever have to be holstered.
I cowitness using suppressor height irons using mid/full size pistols with larger optics. While it might seem counter-productive to use irons to index a red dot, on a fuller sized pistol getting the irons loosely aligned to snap the dot in and then using the dot is pretty quick for first shot lineup and then after that the dot stays aligned for good fast follow-ups or snapping to different targets. But that's with a Holosun, an Sig Romeo, and a Trijicon.
None of those are for carry. A stock iron sighted LCP MAX is 99% of the time carried, sometimes moving up to a Glock 26 with illuminated irons. I'm a big believer that "one in the hand is worth 2 in the drawer at home" when it comes to carry, and the bigger the gun the more likely it is to be left at home.
Agree with stock iron sights for carry. Speed is more important than accuracy for short range, and you have less things to snag on clothing.
With the disclaimer that good red dots are faster in almost every circumstance. I mean to be clear how much of an outlier I find the MicroReflex to be.
