This is easily the most affordable red dot sight you can trust your life to. I bought this having been recommended by an experienced acquaintance to replace my budget Truglo XR21 I got from PSA, which straight up did not have functioning shake awake.I am happy to report that the shake awake function is extremely reliable on this sight, and it has easily held zero thus far at 400 rounds in 2 range trips, I expect it to hold for many more as well. I mounted this on my P365 and it sits perfectly into their factory optic cut.The one issue is that the brightness adjustment buttons on the side protrude a bit. I am right handed, so this caused issues with both my Black Arch Protos-M, and carbon fiber serpa holster (unsure of which brand it is) with the contact between either the holster or my own body automatically turning up the brightness due to how close it is drawn in to my body to be concealed. I was able to fix this by simply gorilla glueing a Danco #61 O-Ring (9/32" O.D. x 5/32" I.D. x 1/16") around the problem button. This provides enough of a buffer to prevent the brightness from changing in any holster, while still allowing me to access it to change it manually. It has the added comfort benefit of not having any sharp or hard edges that could make more future minimalist carry I may try uncomfortable. However, I am sure you could 3d print a piece to buffer here as well, or shape a rubber washer to make it more aesthetic.

First and foremost: THIS OPTIC FITS THE SIG P365 FUSE, even with the screws that are provided - you just have to use the little silver buttons that come with the gun.This is only 3 stars because I haven’t taken it to the range to zero it, yet.But it fits perfectly, and there is no give or movement. The dot is pretty crisp, but I have astigmatism, so take that however you’d like.Other than that, if this ends up working well, I’d say it’s a pretty good optic for a really good price!I’ll definitely update my review as soon as I actually put at least a hundred rounds through it, AFTER it’s been zeroed.//////////////////////////////////////Update: It held zero after putting a few magazines through it… would definitely recommend it if you’re not wanting to cough up a kidney for an optic.

It's just right for my pac sol picatinny suppressed barrel ruger. Very little adjustment needed. Seems to be shake awake but it's not advertised as such. I've only used it for about 50 rounds. It's very useful. Update I've run about 300 rounds and the only thing that looks like it might be inconvenient, is the fact that after a couple of years I'll have to remove the optic to install a new battery. That seems like a long way off at this time but it will take some time and diligence down the road.
