Mean and "GREEN" Review by Fugitive-9mm
When they were first came out I had to wait six weeks to get one, and it was well worth it...I use it a lot and its been thru a lot, no problems what so ever...Seeing the Green in the day light, especially the first time is unbelievable compared to the red, I also on occasions move it to a different gun and its so quick and easy, plus the sight picture has little effect, everyone that I hunt and shoot with have also purchased one, its a got to have deal...Rich (Posted on 2/8/14)
Excellent sight, sometimes problematic switch. Automatic shut off? Review by Abuelo
4.5 In XDM. It looks good on the pistol (does not appear to be a cheap add on). The hand switch and device are well placed to do the intended job. It was simple to zero. I had to be very careful about switch. I have a new minimal type IWB holster and the exposed switch has a tendency to activate when holstered. I am not confident in automatic shut off. I have holstered my pistiol by my bed for the evening or left it hanging on the peg in gun safe and when doing PCI upon retrieving weapon found that the batteries were drained. I always keep spare batteries in my gun safe and car so this is not a major problem. (Posted on 12/27/13)
Best Laser Review by Lucky
I own both CT and Viridian and I chose to use CT hands down. I've had more problems with Viridian than I can mention here. Viridians customer service treats you like your a pain in the butt for bothering them with little to no help at all. CT is the best bang for your buck by far! (Posted on 11/29/13)
203 green Rail Master Review by shadepuppy
I completely agree with Fran’s remarks. He or She has hit the nail on the head. Now that I’m on the verge of Codgerhood
my eyes can no longer focus on different planes like I could when I was young, iron sights are useless,even with tri focals
I can still see the perp and better yet I can still see a red or a green dot on a perp…..if it were not for lasers I would be reduced to a spray and pray defense.This is my 4th Crimson Trace Rail Master, all are still working perfectly, I have them on AR’s and Glocks. CT makes a fine
product that does exactly what it is supposed to do and is durable as well, worth every penny. I also agree with Fran about lights mounted
on weapons ….IMHO …it screams shoot me I’m right behind this bright light …..it’s almost like giving the bad guy a laser

CMR-203 Green laser Review by Fran
Have mine mounted on a Walther PPS 9mm. Been working on this gun for quite some time to get what I wanted and a green laser and a holster to accept it with a laser was part of that.
I love the laser. As a "senior citizen" with less than 20/20 vision anymore but a former LE firearms trainer for almost two decades, I know whats important in such a gun, laser, holster combo.
After finally finding out that CT had a green laser to fit my gun, I got one right away. It works great, even in bright sunlight, over the red dot. I have a red CT laser on a revolver but I like the green one better.
Had a holster made for me from Multi Holster that goes both inside and outside the waistband and it doesn't turn on the laser at all.
As for the light/ laser combo, Having the light mounted on the gun itself can be hazardous to your health. I have a tactical light I can use in my off hand and know how to use it. Don't want a light leading a bullet back to me from someone who has located my gun hand because of the light. I can move the light away from my body
and still keep my gun on target, with or without laser.
I have laser zeroed in at Max distance of clear space in my house and a defense plan for defending my home and family and I occasionally do a practice walk through. At the range, I can hold the gun even upside down or shoot from any position and where the green dot is is where the bullet is going to go too. Great product. Don't want or need a light mounted on my gun. Learn to use a tactical light properly and you will see the advantages over the combo. (Posted on 10/19/13)
Disappointingly limited, half the product for 2/3 the price Review by Nerotik
The laser works well and is highly visible but I find it disappointing that it is only a laser and not a laser/light combo. I purchased a Viridian C5L 250 lumen light and green laser combo for only about 100 bucks more. It has the ability to strobe the light, the laser or both as well as solid on light, laser or both together. It uses the same battery and is windage and elevation adjustable, fits anything with a rail and has on/off buttons on both sides right where your supporting hand fingertip rests for quick and easy activation. Press both buttons together to change laser/light settings. I have had it mounted to my EDC for 3 years now and it hasn't given me any problems. I have been a fan of CT since they hit the market years ago which is why I am disappointed in the limited features for almost the same price as a competitors superior product. I hope to see a CT version of the C5L for a competitive price soon. (Posted on 10/2/13)
Great sight, poor switches Review by Ray
The two switches protrude too far and click the laser on when holstered. Need device on side of sight to protect switches from turning laser on. (Posted on 4/17/13)
Fast acquasion and improved accuracy in broad daylight. Review by Vern
The new CMR-203 Geen Laser has greatly improved my accuracy and speed of acquasion. After a few minutes of tweaking the laser with the new hex tool (with a nice big green handle that helps to prevent it's loss), I put thirty six rounds through my new Sig P-226 40. I set a new target at fifty feet and put the next 12 rounds within one inch of dead center. I could never have done that without the new GREEN CMR-203.
Thank you CT for a great new laser. This is a serious improvement in gun accuracy and acquasion speed. I would love to have a bright green laser on a CCW pistol. Maybe future battery development and laser engineering will make that possible.

CMR-203 universal Green laser on Sig P226 Review by VL
This bright green laser is so much better in daylight. It provides much faster target acquisition even in broad daylight. Aside from having to have a custom holster made, I have nothing but praise for this new Rail Master Green Laser Sight from Crimsontrace. My accuracy at 50 feet in broad daylight is much improved and much faster. (Posted on 3/26/13)
Great fit and profile. Review by Sean
I added this green laser to my Springfield XDS and it fits really well. The polymer laser outside matches perfectly and I only had to make a minor adjustment to laser zero sight but after that the laser does not drift after 400 rounds, still hitting within a inch circle. The green is so much easier to pick up during a sunny day, I was having some issues seeing the red dot in from another weapon. I would recommend this laser to any and all my friends that have firearms. (Posted on 3/1/13)
Outstanding brilliance and easy adjustments Review by Booneknives
Fit my Glock 19 perfectly and was sighted in in just a few minutes. Easily seen at 50 feet, (even much further if shooting requirements dictate the need.)
Made in USA too. I LOVE IT!!

Great laser sight. Easy to install and sight-in. Laser is clearly visible out to about 75 yards on a sunny day. Review by Daniel
Mounted laser on my glock 21. The CMR-203 was easy to install and sight-in. I shot about 50 rounds and the laser was still zeroed in.
Just for kicks, I took the CMR-203 off my glock and mounted it on my Benelli MR-1. It took just a few minutes to sight in and it worked great on the rifle. The green dot was easily visible out to about 75 yards.
Guess I have to buy another one now. (Posted on 1/24/13)
Handy for Tactical Use Review by Yoshi
Tap touch on & off is a brilliant feature, adjsutable features allow for user adaptability, & nice looking as well. (Posted on 11/13/12)
Great product - highly recommend Review by KenK
I did some shopping and comparing before selecting the CMR-203 and I’m very pleased with it so far. Mounted it on a Sig Sauer P229 Elite and the fit, form and function is perfect. The laser is extremely bright. What more could you ask for and made in the USA to boot. Great product! (Posted on 10/26/12)
