Most Helpful Positive Review perfect in home and range shooting laser
The laser works perfect and can be used for different scenarios (range, self defense ) my only stipulation if used on a carry gun you might need a specialty holster becuze my iwb and owb don't fit the laser attached.
Most Helpful Negative Review Not stable
Every time I shot my pistal the light had to be readjusted. I reset it up from the beginning and fired two shots it lost its postion again and again. I' like to return it. PLEASE Pros: easy to put on Cons: will not hold postion

Joe Strickland

by Handsome Joe, from MS, United States Written on February 27, 2022
The order was processed and delivered in a very timely manner. I have not had the time to adjust the sights but I have another unit on another Glock as sighting it in was a breeze. The Glock and with the Crimson Trace fits nicely in my leather holster and it is a must have for Concealed Carry. If I upgrade to another Glock, I will definitely order another Crimson Trace unit to attach to mu upgrade.
Pros:
  • Ease of use
  • Ease of use/install
Cons:
  • No Cons
Best Used for:
  • concealed carry all year
Would recommend: Yes

Installed on Glock 44

by Hardwarehank, from NY, United States Written on November 25, 2020
Although description doesn’t show Glock 44 for fitment, since frame is sized as a G19, I decided to give it a try. Fits the G44 perfectly, hitting 6” steel plates @35 yards. Easy to sight in, laser visible to apx 40 yards outside, more inside. Very compact, would definitely buy again.
Pros:
  • Compact & light
  • Easy Mount
Cons:
  • short battery life
Would recommend: Yes

First laser sight

by Good Product, from NY, United States Written on July 10, 2017
This product is advertised by the maker to be sighted in at 50 feet....not so at 50 feet it was hitting about 4 inches high and 3 3/4 inches to he left. I asked 2 other people to shoot the pistol & they experienced the same pattern...so it was not me. After it was sighted in it now hits where you put the laser. Overall (Especially for the price) it is a good deal.
Pros:
  • easy installation
  • good value for the money
  • looks good on th pistol
  • once sighted it is very accurate
Cons:
  • position of the power switch
Best Used for:
  • self defense practice
Would recommend: Yes

Accu-Guard Laser Sight

by Howard C., Verified Owner from CA, United States Written on April 18, 2017
Nice design with excellent fit. Very easy to install. Small, easy to turn on/off. Laser very bright. Great bang for the buck. Battery life okay but could be better. Looks like a factory part. Blends in well the gun.

Glock Accu-Guard

by hockeydoc, from FL, United States Written on September 4, 2016
This was the only Crimson Trace laser available for for a Glock 21. Easy to install. So far, after 200 rounds, it has stayed in place, holds it's zero at 15 yards and is dead on at 7 yards Seem to be just what I needed. The on-off switch is a bit far away from my trigger finger but if you keep your index finger in a safe position out of the trigger guard, the on-off switch is just a bit of a strech further and you can always use the weak hand to hit the switch on the other side. The only negative is no automatic intuitive on switch. Otherwise it works fine especially for the price.
Would recommend: Yes

Nice entry level product but not something I want on my gun

by Roland Alonzi, Verified Owner from GA, United States Written on July 30, 2014
Let me start by stating three things:

1. This product sells for about $100.
2. This product works as well as you would expect for something that costs $100.
3. You get what you pay for.

For the novelty of it, I wanted to attach a laser sight to my Glock 17 Gen 4. I got the DS-121 and immediately attached it to the firearm. It was more difficult opening the blister package than it was to install it on my firearm. I used it at the range and it worked well enough. Then I noticed that it would turn off after a few consecutive shots. I would turn it back on, only to have it turn off again. Finally, I gave up and took it off the gun.

Short Review: Nice novelty, but not much more. Spotty performance shows that you get what you pay for.
The Good: Price, ease of installation, adjustments.
The Bad: Spotty, inconsistent performance.
The Ugly: Laser would not stay on after consecutive shots.
Would recommend: No
