Vortex Optics Defender-CCW Micro Red Dot Sights - Motion Activation with Auto-Shutoff, Shield RMS Footprint, Fast-Rack Texturing - Unlimited, Unconditional Warranty

Fits my M&P Shield M2.0 Metal Carry Comp with a plate. Had to get taller iron sights to cowitness. Had it for some years now. I would trust it with my life. Holds zero, nice and bright and battery last a long time. Still change it out every 6 months. Love that the battery compartment is not under the optic so easy to change and don't have to re-zero.

Had it mounting on my Glock 17 that was not MOS. It sighted in easly and 17 rounds at 7 yards in 2.5 inch group. Thus the entire target center is gone. Now placed on my Glock 47 MOS with same results. Also have it mounted on my Glock 43X and yes same results! I love this Red Dot would never buy anything else. For as long as the battery last replacing it isn't the fastest but i don't have to rezero it!! Shake awake is great and adjustable dot intensity is wonderful. Did i mention the life time warranty!

I put this on a Glock 43X and fit directly without a mounting plate. The buttons are large to be able to manipulate with gloves on and the green dot is easier to see. Like with all red dots, max setting does give it the halo effect. I other high end red dots that do this too, so I wasn’t surprised when it did on max setting. Hangs off the slide a little but not a deal breaker. Had to turn up the brightness setting when shooting at the range and was sighted in after 3 volleys. It held zero after several drills. Approximately 200 rounds. I’ll update further after more trips to the range. Would recommend for the price and direct mounting feature. I can still use irons sights with this red dot and prefer this red dot over my 407k.

This is one awesome sight and got a great deal on it . It fits great on my hellcat and it looks even better than the wasp .i recommend this sight .

Update 4/18/24: I have had this red dot since March of 2023. I have shot probably 3000 rounds through my shield plus with this red dot installed. It has never lost zero. This is not my carry gun and seems to go through batteries every six months. My only complaint is the battery life. I have not drop tested it yet or been real rough with the red dot. Seems very reliable and you just need to watch your battery life. Very good purchase. This is by far the best Vortex red dot yet. Now, that's not saying much. I have this mounted on a shield plus. Pros: It appears to be a very solid optic. There are some brutal torture tests on Youtube for this optic. The top load battery is amazing! The amazing included screws, seriously all optics should come with this. The included tool is nice. The glass is clear, the site picture is amazing. It co-witnesses just fine with the factory shield plus sights. The dot is super bright! Cons: The dot is very low res, it's crisp. The blinking can be annoying though. The windage and elevation turrets click, but it is not very audible and not tactile at all. The 14 hour auto shut off is very weird. Most dots are an hour or less. I will never understand that time frame and that definitely has an impact on the battery life. I have shot about 300 rounds so far with this on the shield plus and it has held zero no problem. The flickering led emitter is kind of annoying, but it hasn't impacted my shooting. Based on the built quality alone, I will keep it. If the only bad thing is that the battery lasts a year and it flickers, I won't have much to complain about. Update: Six months in and no issues, battery just died. Having the battery die within six months is not great. I do not carry this and I would have thought it would have lasted longer. Luckily the batteries are cheap and top load.

This fit perfectly in my edc. Clear and easy to see cowitness sight on my S&W Shield Plus.

I bought this for my G43X MOS and it was super easy to install and love the small footprint. I can also cowitness with my ameriglo night sights. Haven't been out to the range with it yet,but did use a laser boresighter to align the red dot. I'll update this if there are any issues,but I doubt there will be any issues.

Love vortex. Great conceal optic Love the knarling, makes racking much easier
