Products to Elevate Your Confidence in Moments That Matter

In 1994, Crimson Trace developed and sold its first laser sight - an internal system for GLOCK pistols, known as the GLS. Two years later, the newly patented, user-installed Lasergrips product line was unveiled at the 1996 SHOT Show. Over the years, the engineers at CTC have been dedicated to constant improvement and the evolution of products. As we approach our 25th year, Crimson Trace is pleased to add electronic sights, precision riflescopes and sporting riflescopes to our collection.

It's a Different Fit, but YES, It fits the G43 Just Fine
5 Stars
It's a Different Fit, but YES, It fits the G43 Just Fine
Fits the Glock G43 - but it is a snug fit due to design change from models for other firearms. Some reviewers have criticized the LG443, saying it does not fit the G43, and, based on my prior experience with CTC lasers (this was my 5th one), I thought the original one I received was defective. I don't know if Amazon has a policy against showing pictures of guns, but I have included a photo of my G26, with the older style CTC laser LG-436, comparing it to the new LG-443 for the G42 or G43. One of Glock's, salient points is to replicate the trigger guard along their pistols, no matter the caliber and overall size of the gun. But while the Trigger guard on the G26 and the G43 are virtually identical in squared off design, CTC has smoothed the LG-443 compared to the LG-436. It does make it easier to holster the gun when outfitted with the laser.But when installing the LG-443, you have to (mildly) force it into the appropriate shape to hold onto the trigger guard; then keep it firmly compressed, while inserting the small screws holding the two sides together. Once on, the laser operates just like any other CTC trigger guard mounted laser. For those who are new to CTC lasers, this probably will not present more than a momentary grimace; but for those of us who were used to the fit of the unscrewed laser, where it would remain on the guard, needing the screws only to hold together the two halves during usage, it may seem as if there's something defective about this particular item. I assure you, it works just fine.Unfortunately, when I first tried installing the LG-443, thinking the required forcing of the halves indicated something defective, I called CTC, and without argument they immediately sent out a replacement. It was only after receiving the replacement and finding it required just as much effort to install as the other, that I compared the two models, and realized they had made a design change; one that, although beneficial to he user, required slightly more effort to install.The only downside I can see to the change is that I'll have to be more careful when changing batteries, but mine last several years, so I can live with that. CTC states their red lasers last for 4 hours of use, and their unique design of turning on only when the gun is being gripped for shooting, and automatically turning off after the shooting grip is relaxed, makes that 4 hours last a lot longer than one would expect.

5.0 out of 5 stars Excellent Option for me..
Reviewed in the United States on January 14, 2020
I did a lot of reading before I decided on this laser. I bought the G43 with Tritium sights and am extremely happy with my choice so when I decided to add a laser sight I wanted the most comfortable, reliable and convenient to use. Shooting in daylight I’m very comfortable with my iron sights and they will always be my primary for target practice but I felt I needed a little boost to my night capabilities. Bulk is a problem as I am small so it’s all I can do to carry this size gun concealed. I use a belly band and a Sticky Holster depending on what I’m wearing. I modified both holster slightly to accommodate the laser and it worked perfect. This isn’t a replacement for iron sights but an advantage in certain situations. So far I am very happy with my choice. BTW gun was unloaded and no cat was harmed while taking that pic..... she definitely had a blast though.
