Sig SauerRomeo Zero 1x24mm SpectraCoat Lens HD Lens Ultra-Compact Micro Reflex Sight

I highly recommend this product. This is a very good optic although the screen is not large the romeo zero works great and is very light and does not add appreciable weight to the 365 XL. The sight was easy to install set up and zero it has held zero. The dot does not wash out in good light but I have only used this at an indoor range. Under low light conditions it is excellent. The fit and finish of this sight matches my 365 XL perfectly, and if I did not install it myself I would have thought the 365 XL came with the sight from the factory.Time will tell if the Romeo zero is as robust as my RMRs which are great optics as I only have about 100 rounds with the Romeo zero on the 365 XL. I do agree that the on and off button is difficult to access if you have chubby fingers, maybe difficult even if your fingers aren't chubby. But the auto off (sleep mode) when the pistol is motionless and auto on when the firearm is picked up negates the reason to use the button. The 365 XL with the Romeo zero sight fits in my Desantis concealed carry holster I bought for use with the original iron sights.Positives:great fit and finisheasy to install,easy to zero,holds zero,sight acquisition is faster than iron sights to get on target for follow-up shots.The romeo zero lengthens the effective range of the 365XL as the ability to acquire targets at distance is better and shots are more reproducible than with iron sights.Cons none with the auto sleep and auto on when picked up

I have been a Gunsmith for 44 years and have mounted more RMR type sights than I can remember. The Sig ROMEOzero was very straight forward in its mounting. It was mounted on a Glock 27, .40 S&W utilizing a dovetail mounting plate. The majority of these sights are metal but the ROMEOzero is a polymer housing. This particular mounting was for my personal EDC firearm and I can honestly say I have mounted more different brands than I can remember. I chose the Sig because I wanted a sight that was small but still presented an excellent sight picture. The instructions from Sig were well written and would serve a shooter who has never mounted this type of sight. Of note and great importance is the warning of not to over tighten he mounting screws because it could deform the polymer and cause the sight to malfunction.My first observations were the automatic waking of the sight with the slightest movement. Yes, this is going to cause the sight to be on with the daily movements but off whenever the firearm is still. The presentation of the red dot is very impressive when bringing the firearm up to the shooting position. I found that I needed to bring the intensity of the red dot down to mid level of brightness. Doing so gave excellent presentation in bright sunlight as well as total darkness. I urge the shooter to experiment with this to find what works best for them.Range time revealed the need for sight adjustment. Shooting at a 7 yard distance I fount he elevation to be perfect but I did need to adjust windage to the right. The adjustment screws are well defined with arrows indicating direction of travel. They are also pronounced with a solid felt click for each moment of travel. After adjustments over 50 rounds were fired with the sight holding perfectly. All screws were checked for problems and none found. I am also an NRA pistol instructor and Training Counselor and would urge anyone to consider this sight or one like it for defensive shooting. It gives the shooter faster sight acquisition and far better grouping than standard “iron sights”.Lastly I paid for this and have not been compensated in any way. Be SAFE…..Shoot WELL

Perfect fit easy to set up and use. Would buy again

Battery is not captured, just in between slide and sight unless you use the included thin metal "shield". Two sets of screws included. One set is for mounting to P365(?) I guess. The screws have unthreaded shoulders that act like bushings inside the red dot base. The ones for the Sig mount pass thru the holes in the base like they should. The other 6-32 screws also have bushing/shoulders and do not pass thru the base properly. I was told by Sig tech support to "just push them thru". That is what I did and they just spin in my S&W Shield with optics cut. I found some 6-32 switch plate screws that work for now. I am going to zero the sight if possible and run 50 rnds thru pistol to see what happens. The only controls are/is a button inside the tombstone just this side of the glass (?) You can supposedly use it to turn off and on and adjust brightness. The brightness adjust does work. Accessing that button is whole nuther issue. My man fingers cannot access the button. I have been using a flat screwdriver blade. Not ideal and neither is the placement of the button. Probably the absolute WORST place they could have possibly put it. The MOTACS does work but I see the adjustment of the brightness of the dot being very problematic. There is no brightness level that will work for all conditions so being able to adjust it quickly would be necessary for any red dot. That is not going to happen here. You get what you pay for and sometimes what you think is a tool turns out to be a toy. No way I would bet my life on this thing.

Decent sight. Works well with Sig 365 macro

I've been looking at this sight for quite awhile now. In researching the sight, I came across 2 main complaints. 1, that the sight is made out of a flimsy plastic. 2. that the power/brightness adjustment button can be hard to access.Very happy to say that issue 1 has been rectified. The site i bought came with a aluminum shroud that should protect the plastic frame of the sight.As for issue 2, well, I have big fingers and short finger nails, so ya, the power/brightness button isnt exactly the easiest to access bare handed. This is a very small sight for a very small pistol, so i think i can accept that. Especially sense the sight automatically shots off after 2 minutes of no movement and turns back on when it senses movement.We'll see how long the battery lasts when in this mode.

Holds zero works great!
