I found it fast to acquire the target. The 6 MOA dot is easy to pick up.
The green was easier for my eyes. your mileage may vary.
You can replace the battery without removing the optic and losing zero which is a big plus.
It appears to be durably built.
It’s built for slim subcompact pistols and keeps the footprint small.
It is a single-dot only. No multi-reticle option, so it’s less flexible than some other Holosun models.
It has a small window but this typical with most micro pistol optics, and it takes good presentation and practice to find the dot quickly.
The mounting can be a hassle. The K-series footprint may require an adapter plate on some RMSc-cut slides, which can affect sight height and co-witnessing.
This optic makes the most sense if you want a simple, rugged carry optic for a slim pistol and you prefer a green 6 MOA dot over red. If you want multiple reticles, a larger window, or a more universal footprint, another model may fit better.
