Bought a Glock 48 that had this on it already. It really made the weapon an awesome tool! Will be putting another on my 43x

Awesome product

I have Crimson Trace lasers on all of my pistols. My latest CCW is my trusty Glock 43. This sight laser is just as well made and accurate as all my others. Just buy it. It’s perfect (and no, it doesn’t need a master on/off switch. That’s crazy talk)
 Thanks CT, for making such kick-ass products!

Quality, perfection, as usual....

Just received my laser LG-443 installed it .Went to fill out warranty card and free battery form found out that the serial .# is on the in side of the laser. There is no place in the book that tell you were the serial.# is located before installation. No warranty or no free batteries. Not happy with this purchase...

not happy

ON 3rd ONE (YES, 2 GLOCK 43's, 1 OTHER)... SHULD BE MANDATORY! 
 
 I ABUSE MY WEAPONS... THEY GET DROPPED... DROPPED ON PAVEMENT, IN WATER, etc., etc -DURING PRACTICE & TRAINING! NOT INTENDED... JUST INCIDENTAL TO JOB (and the fact that Im a klutz). THEY - R- FLAWLESS!! ALWAYS WORK!! 
 
 I RECOMMEND as 'MANDATORY EQUIPMENT' TO ALL MY STUDENTS!! MANDATORY!!
 
 PS: SAW 1 RATING ABOVE RE: "MOVES AROUND" ... ?? THEY R ROCK SOLID IF MOUNTED CORRECTLY (AGAIN: EVEN IF DROPPED) - SO NO NEED TO WORRY ABOUT THAT. C'mon.. the frikin Military uses these things!)

MANDATORY!!

The site moves every time the gun is holstered and drawn. since the Glock 42 and 43 do not have rails there is nothing keeping the front of the unit secure and it keeps moving. Every time the weapon is drawn the laser is pointing in a new direction. Crimson Trace says some movement is expected. Not on my guns it's not. I do not recommend this to anyone with a Glock 42 or 43. I hope other Crimson Trace products are better than this. Customer service said it is fine and offered no support or suggestions at all.
 
 Not happy.

Not accurate - keeps moving

The LG-443 fits the Glock 43 extremely well. No alterations to the Glock 43 are required. The LG 443 even keeps your knuckle away from the sharp edges of the trigger guard that several users of the Glock 43 have complained about. The factory setting had rounds hitting a bit low, one adjustment and now it is dead on. Several magazines fired and the laser hasn’t moved. Great product and you have to love that it is made in the USA. 
 
 As others have mentioned, if you have big hands, getting a two round magazine extension makes it so that your hand will naturally land on the activation button. Without a magazine extension it does take a bit more effort to hit the button right away. (more of a Glock 43 Issue than Crimson Trace issue)

Great fit and a better finish than Glock

The is a well thought out laser pointer for any type of hand gun. We have it installed on a Glock 19 and 42. We love it as the ease of use is very well defined
 For those that Bi**** about no off and on switch I suggest to not buy this product. Buy one with a off/on switch instead. This great product is great product as is and we love it. Thank you for this product.

Great product

Have had this on my G42 for 18 months now. I carry this as a back up and shoot 30 or so rounds monthly and the sight has been flawless including still having the original batteries. I was happy to see that I could just take this off of my G42 and install it onto a G43. Could not be happier with this product.

Couldn't be Happier

Well like so many others that wrote a review - I really can't find fault with the laser sight, and really like it, easy to install, easy to zero, easy to use, even bright enough to use in daylight! - But I really wish the unit had a master on/off switch, then I could give it 5 stars! Yeah I would like to train with it some, but would also like to be able to shut it off for extended shooting sessions. I bought the laser/holster combination and really am glad I did, the holster at least reduces the likely hood of inadvertently activating the laser.

LG-443HBT laser Great for G-43

I installed it on my Glock 42. It just makes a great package a perfect package. I am getting another one for my Glock 43, just wish there was a master on & off switch.

Great Laser but no master on & off switch

I hate to give this 3 stars but without the master on/off like my LG-436, I cant give it 5 stars.
 This is my 3rd CT laser and I love them. They hold up well, fit and feel is AWESOME!
 The pressure switch is very intuitive.
 I have a big issue with this not having the master on/off, I like to practice with and without the laser on. I want to be able to pull this in a defensive situation and not have to worry if the laser comes on or not and know I am prepared if it for some reason were to not come on.
 I have never had a CT fail but I have had another brand fail.
 Not sure the reason for not including a master on/off.

No master on/off

Great idea and works well but no on off switch!
 I'm going to return it!

No Master on off switch

After owning other C/T laserguards, disappointed that the G 42 laserguard does not have a master on off switch!

No Master switch on and off

I had one of the first generation Crimson Trace lasers on my Glock 21 wherein I mailed the gun to Crimson Trace and they installed the laser in the trigger guard. The activation switch was the same as this model and it was excellent. Can't imagine the wife trying to remember to find the master on/off switch during a stressful situation. I have the factory installed laser on my S/W bodyguard 380 and it is a pain in the **s to activate. This is simple. Makes the gun look like crap but other than that.

Excellent

have this lasergrip on my G42 for some time now and love it.

great product

I got a new Glock 42 for the wife and added latter added a Crimson Trace laser. Took just a few moments fine tune the laser and it is awesome. Seems a bit expensive at first but a saved life because of this add on will be priceless, Easy for the wife to use with out thinking about it and has given her confidence that she did not have before. I have a different brand in my Glock 26 and wish I got the CT instead.

Love it!!

I own a new Glock 42 and would not have any laser BUT a Crimson Trace. I had to mess around a bit and fine tune my laser but it is awesome. Seems a bit expensive at first but a saved life because of this add on will be price less, if I ever have to use it!

Great Product

Battery was mostly dead before I got to the range. Very disappointed. Pistol needs to be stored in blade tech holster as it's too easy to have the button pushed and the battery wasted.

I love this sight. Works well on G 42, sights in easy at the range, no real need to remove for routine gun cleaning. No master switch, but I think its great without one. Good conceal carry case too with no chance of activation. There is nothing not to like.

Love it - works great.

no adjustment needed after install-eveyrthing lined up. as to the 
 master on/off switch,back off your middle finger a little when you first grab the gun. that way you won't activate the laser until your ready.
 I recommened getting extensions for the magazine. the extra 1/2" I
 picked up really helps with my grip.

works for me

After owning other Crimsion Trase Laserguard sights, disappointed that there was no master on off for the G 42 Lasergiard
