    • Quality Sight
Style: 3 MOA Red Dot
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 ... show more

    • Why put the power button there lol
Style: 3 MOA Red Dot
Bought three of these optics to use on various HGs. As long as they're the right foot print they fit great. They come with a metal shroud to protect the optic but doesn't come with a cover. The glass is clear and dot is visible. The only thing I can say would be a hindrance is the button to turn it on is quite problematic and hard to reach. But im happy with my purchase ... show more

    • Poor Design Features
Style: 6 MOA Red Dot
This isn't my first Sig red dot and I'm very happy with my other ones. However this one is giving me pause. It's design seems kind of clunky and cheap where it matters. It comes with 2 sets of screws, not sure why since the instructions doesn't say. Only which ones to use and they seem slightly too long. They don't seem to seat well but I'm hesitant to over tighten them. The instructions say to tighten to 9 inch lbs, but who had that tool laying around except a gunsmith. The red dot itself is in a plastic housing that slips into a metal housing for better protection. I'm ok with that, my issue is with the battery. it's loose at the bottom of the plastic housing and relies on the metal housing to hold it in. Not good. Seems to work, but cheaply done. My next issue is a big one to me. The placement of the button that turns it on and also adjusts the brightness. It's inside the housing next to the glass making it impossible for a normal man fingers to reach. As much as I'm tried, I cannot get my finger in far enough to press the button. So how the hell can I turn it on???? Let alone adjust the brightness? I read one review where someone mentioned having to carry a flathead screwdriver to get in there. That's ridiculous! I didn't think that could be true. It is !!! The other issue I have is how you adjust it up or down. My other Sig red dots have a slot that will allow you to use a dime if you're in the field and don't have a screwdriver handy. This one requires a very small allen wrench that is supplied. It's so small and thin, I would be afraid to take it to the range for fear of losing it. Then you're SOL if you need to adjust the sight again. I really had high hopes for this based on my other Sig red dots, but this is in a class by itself. The junk class. If you can't turn it on, why even have it. The down side is I don't know of another Sig red dot that will fit my P365 Macro. However, if I find one by another brand, this one is coming off in a heartbeat. Heck, I may as well take it off now if I can't turn it on. I started out with this at 3 stars but the more I wrote, I couldn't leave it there. This is far from Sig's best work and they should be ashamed to sell this. I'd rather pay more and actually have a functioning red dot that I can turn on and adjust. I can't in all honestly recommend this. ... show more
