Reviews & Ratings for Crimson Trace CTS-1550 1x 3 MOA Reflex Red Dot Sight — 22 reviews — Page 1

Replaced my original with this one. Works great. Pretty good price. Plenty of screws!

The sides/edges of red dot extend very slightly past the width of the slide of my G43x MOS; but it doesn’t seem to interfere with the holster or snag anything… The box was sealed with a sticker when it arrived in the mail; and inside of the box along with the red dot and booklet were 3 hex keys in a small plastic bag… Two of the hex keys were tiny & identical and the third hex key was a half size bigger; however none of the hex keys seemed to fit into the red dot in order to adjust the elevation or windage � I attempted using the smaller hex keys with no luck and I didn’t want to damage the the unit… I was literally minutes away from returning the red dot unit until I randomly found the correct hex key in a toolbox at home… Odd situation, but not a deal breaker for me… After making a few minor adjustments, everything seems to be fine.

Fit to a S&W Shield Plus with no problems, it looks like the red dot S&W fit as an option to the pistol.Polymer body is solid and looks good and for the price is ok. At the range it was easy to zero and surprised me by how much accuracy was improved. For me the dot was the right brightness and easy to see. A lot of people dont like the polymer but will buy a pistol with a polymer body. If S&W fit this as an option, I would think it would be a reasonable balance between cost and quality.

Great little red dot. Installs directly onto my Kimber Mako R7, alignment posts in the slide fit the registration holes on the bottom of the red dot for a precise and repeatable fit. Nice because it's the exact width of the slide - so it doesn't hang over the side of the slide like other red dots. Red dot has a good size for me, good brightness in all light and easy to pick up. Slight field curvature at the edges if you specifically look for it, let's be honest, but this is not noticeable when aiming. Also, slight greenish tint if you look for it, but again let's be honest, this is not noticeable when aiming. The battery installs underneath, so in 2 years you'll be taking the sight off to change the battery - common CR2032 - and re-zeroing. This is acceptable for me because of the compactness of the sight that fits the Mako R7 so exactly. Use the supplied allen key wrench for zeroing adjustments. Once set, holds the zero precisely for years.

Got this super cheap, great for a range gun at the price. So far works and holds zero.

Purchased this product to go on my wife's Smith and Wesson 9mm. Very sleek, low-profile, good looking and deadly accurate. Easy to install and calibrate.

The auto adjust to ambient lighting, sucks?
If you are in a dark room looking into a lighted area, the red dot is almost invisiable.
when you reverse the action light room into dark the dot is bright?
If I have to have a light shining on the sight to see the dot?
I might as well have a blinking light on my head.
There is no stealth advantage having to to in the bright light to make my RDS work.
Be happy to sell it to anyone that likes an auto adjust RDS?
I may just move it to a hunting gun the light is about the sae as your target!

I REALLY like this sight! I like the fact that it has the ability to co-witness the front sight with a"groove" at the rear. Really good design.

After roughly 300 rounds on a .22 pistol, the red dot lost its zero. When trying to re-zero the dot, the windage and elevation adjustments were not working properly; adjustments did not move the dot far enough down or to the right. Upon closer inspection, I observed that the emitter came lose from its housing which is why the adjustments were not working. I contacted Crimson Trace and they stated that they would send me a replacement once the CTS-1550 was back in stock. Six months later at the time of this review and CT claims that the CTS-1550 is still not in stock.

Finally found a good red dot to use on my M&P Shield Plus. Seems to be holding zero after a couple of hundred rounds. Was on sale so it was even better. Seems to be very solidly built. Plus fast free shipping!
