ホロサン ドットサイト HS407C X2 HOLOSUN

Not so bad for astigmatism, totally usable. Super clear, small, perfect for my PC9.

I recently mounted the HOLOSUN 407C/507C-X2 on my Glock 19, and it works perfectly. The fitment is secure, and it holds zero flawlessly even after several hundred rounds at the range. ​The build quality is rugged, and the side-loading battery tray is a huge plus since you don't have to remove the optic to swap batteries. The reticle is crisp, and the solar failsafe provides great peace of mind. If you’re looking for a reliable, duty-ready red dot for your Glock, this is easily one of the best bangs for your buck. ​Mounting Tip: To ensure it stays rock-solid on your G19, I highly recommend using a tiny drop of blue Loctite on the mounting screws and using a torque wrench to hit the manufacturer's spec (usually around 15 inch-pounds).

Got this 3 years ago and it’s awesome battery been changed maybe 10 times in 3 years used in law enforcement

Quality is just what I'd expect from a holosun product. Easily installation, comes with hardware, warranty paperwork inside, and ready to rock. I prefer the red dot over green and at this price point I couldn't beat it.

Yes, all day long and into tomorrow. I love this little sight. It is very compact but it's stout, made of good quality that you'd expect in Holosun products. Target acquisition is excellent, which I was very skeptical of, well really wasn't sure of, I should say. Even after numerous rounds the dot is still on target. Make sure that you pay attention to whether it will fit your slide or not, which someone told me to do as well, hence my choice in this model. It fits perfectly on my compact. I also thought it was a great value for the money I was spending. I would buy this again over and over again!!! It is the quality you'd expect and you won't go wrong with it. I will say that even with the slightest movement, nudge, bump, hard breath or whatever the dot becomes active. Not a negative just saying. I do love this little sight!!
