Vector Optics Frenzy 1x20x28 6 MOA Red Dot Sight w/Extra-Large Window, Auto Shut-Down, Fit for Pistol Cut, SCRD-40

This is a great optic from a company with absolutely stellar customer service. I have it mounted on my service pistol, a Gen5 Glock 19MOS. I love the massive lense. I previously had another smaller optic mounted and I must say that I like this one much better. The larger lense makes the red dot come right up at eye level with ease every time.I use p ammo and it has stood up to that recoil with no shift of zero whatsoever. The red dot is very bright, and on the highest setting there is no doubt that you will be able to clearly see that dot even on the sunniest of days. I did look at the dot through the two night vision modes. They are barely visible in pitch dark but through a Gen2 monocular they are perfect.I wanted to state that if the red dot is not clear you probably have an astigmatism. This is often the case when people.blame the optic. I did have a small issue with Amazon sending me a used optic instead of a new one. The great people at Vector quickly mailed me a brand new optic free of charge. They have fantastic customer service.I carry my pistol with this optic mounted daily on the job and I trust it. Purchase with the utmost confidence.
