Great sight on sig p365xl - Holosun HE507K-GR X2 1x Green Dot Reflex Sight

I love this thing. Bolted right onto my Sig P365XL everyday carry pistol (with its optics cut slide) in just a few minutes, needing a 5/64" hex wrench to remove the Sig rear sight. Small, fits very low, protrudes less than .80" above this slide. I prefer the default reticle, dot with circle, for speed. The dot alone is very precise for accuracy. Very easy to change brightness and reticle, owners manual is clear. The shake awake works fine. Memory keeps your preferred reticle & brightness when you awaken it. Not a red dot shooter, I dry-fired a couple hundred times to get familiar with presentation and finding the dot, then ran 100 rounds through it, precise aiming, no drama. I do prefer this green to a red dot due to old eyes. Been shooting iron sight pistols 60 years, think I'm a green dot convert. I haven't abused it so can't attest to its durability, aside from no problem using it to rack the slide. The provided vestigial rear sight isn't of much use, way too big a slot, but it's easy to ignore. Strongly recommend this one.
