Sig Sauer SOR01300 Romeo Zero Reflex Sight, 3 MOA Red Dot, Black, One Size

The button to turn on and adjust this dot is in a dumb place that causes you to smudge the lens when pushing it. Changing the battery requires removing the sight. Adjustment for windage and elevation gives no feedback and the instructions don't give you much to go on when it comes to zeroing. The only good thing is that it's lightweight but that's because it's all plastic. Just save up for a better red dot

Awesome sight for my Shield Plus and P365. Its made of polymer and matches the stipiling on the P365. It comes with a metal cover or guard that gives you more durability and protection from a fall or everyday use. It's compact and fits subcompact pistols well and is ideal for concealed carry. Installation was easy for both pistols and I didn't have to modify or buy an adapter plate. It bolted right up and was easy to adjust. If you have a Sheild Plus or P365, this is the best sight for the money.

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

Sig Sauer Romeo Zero is working pretty awesome. Make sure you get a good mounting plate though. Cheap plates don’t mount level and there is too much play in the slot. Ordering a better quality plate.

I initially thought that the Motac system didn't work. 1. You have to turn the red dot on first. It will not turn on automatically from the 'full' off setting. 2. Turns off after 2 minutes of no motion. 3. Auto turn on is VERY sensitive to vibrations ! Just stepping harder while walking towards it, to check whether it turned off automatically, wakes it up... I had to actually sit by motionless to confirm the feature 😊 This means it will always be on while carrying or transporting. Hence I'm doubtful of the advertised battery life. That said, I'm happy with it for the price. The slim profile goes well with my Kimber 1911. If you need a plate, it has the same footprint as DeltaPoint and Shield. Searching for a Romeo Zero plate will yield almost no results. I reached the end of the internet, to find this out, so you don't have to 😊
