Crimson Trace LG-420G

Fits perfectly, tight no wiggles !!!Keep coming up with Great products!!!
 Thanks I’ll buy CT

Fabulous 5Star

I've purchased the same laser but with a red light about 7 years ago I noticed that at times it acts up and doesn't light up I have to tap the laser or give it a good jolt in order for it to work maybe there is dust inside, I will have to look into it otherwise it's a great product I love the trigger squeeze-on function, when you need this most there is no time to manually turn the laser on like with other manufactures or models.

Intermittent

Can’t remember when I bought the laser, but it’s been at least 5 years. I test the laser every day when I put the gun in my pocket, sometimes I test it a little long if the dogs see the laser. I thought I signed up for the free battery but don’t think I did. But I’m not sure I need to. Battery is still going strong.

Battery life

Took about 5 minutes to install. Not obtrusive at all. As "married" with the pistol as one of the magazines. Works perfectly. Activation button feels like part of the grip (you don’t know it’s even there; the laser just comes on when you use your normal grip).
 Bright and precise even outside in bright sunlight.
 It has added a much higher level of confidence for times I might be called on to use this home protection pistol.

East to install. Fits precisely. Works perfectly.

I have owned this light laser combo for about a year and a half. Never had any issues with sighting or battery dying from carrying this set up. However just an fyi, holsters will be harder to find. Not many companies make them. Blade tech is the brand I use. But overall, as long as the grip button doesn't bother you, your going to love this product.

Excellent light and laser!

I thought it was a bit to pricey for a laser, BOY WAS I WRONG! WORTH EVERY PENNY SO HAPPY I GOT THIS.

BOY WAS I WRONG!

Off a little when I mounted it but pulled it in with a bore sight laser, works great!! I am happy as a pig in slop, just as I am with my other four CT greens and a red!! What can I say, there is just no substitute for QUALITY !!!

Love it !

Put this laser on my Sig-P365 and one trip to the range was able to dial it in so I can hit with reliability anything from 25 yards in.
 
 The Green laser is very bright and you can easily see it even in the bright sunny days in Arizona, out to about 20 yards. 
 
 Excellent product!

East to install, easy to dial in, works like charm

fits well, activation switch works well but every time you pull the trigger on the release your finger is pinched between the trigger and where the laser attaches to the trigger guard.I hate to have to take a file to a 250 dollar laser to try and smooth it out, should have bought the sig laser, I expected better from Crimson Trace.

not happy

I have owned this product for over a year and a half. It functions as designed. The feeling of the grip button may take a while to get accustomed to; however, it is not a hindrance with a proper grip and I've actually come to like the feel of it. As for the light element, it is plenty bright for most engagement distances you may find yourself in, it can be used in tandem with the laser (either strobing or steady) you can also use the light standalone or laser standalone, the button to cycle between modes is fairly accessible. As for the green laser it is observable at 25 yards against a dark stained wood fence. It is easier to observe than a red laser at equivalent distance. Great product and great support from manufacturer.

Excellent Product!

Easy to install, fits great. Seems to hold zero.

Nice produrt

Excellent sight and I recommend it. The only suggestion I would have is to do away with the button and instead add a touch activation mechanism on the bottom of the trigger guard.

Super sight

Bought my wife green laser guard for her 380 S&W EZ and she loves it but night time flash light is needed she just bought the new 9mm EZ and would like to see a green laser guard tactical light combination made for the new 9mm EZ also wish they offered holsters for guns with laser guards which are very difficult to find. love crimson trace products hope to see new laser guard tactical light combo for 9mm EZ in the near future.

Time for green laser guard tactical light combo for 9mm EZ

Love the laser and gun combined, but no one makes a paddle holster to fit the holster. 
 Very disappointing.

Four star

First, make SURE you write down the internal serial number before you install this device.
 
 The Laserguard comes as two separate pieces split down the middle lengthwise that cup the rail and trigger guard and is held together with 3 tiny black steel hex screws that go in from the left side toward the right side which apparently has tiny inset nuts. Construction appears to be a rugged plastic so it doesn't add a lot of noticeable weight so I like that.
 
 I have removed and reinstalled it several times and believe the holes for the screws on the left side could be slightly larger to allow the screws to pass more easily. One difficulty for me, being right-handed, is trying to adjust the beam when the left-right adjustment is on the right side instead of the left.
 
 It is really difficult to avoid hitting the beam switch (it's on the grip) so my one wish would be to have an additional disable switch on the device for range practice without a beam.
 
 The device seems to retain a fair degree of accuracy between removal and reinstallation but I've only had it a few weeks. It's a little pricey but I can recommend this product.

It works very well but needs a disable switch

Just received it for Christmas from our son for my PPS M2. You have no idea how well this works! You must try it. We took it to the range today to zero it in at 7 yds and it was spot on from the factory. No adjustment needed. A real confidence builder for casual shooters like me. Bad guys need not try me.

Fantastic product!!

This unit does not fit the Sig Sauer P365 XL. It lays such that it pinches the trigger finger on the return. (And even on the standard P365 the tolerance/clearance is not adequate)

Not a fit

They really mean it when it is factory sighted, silver dollar size grouping at 15 yards with the LC9. 
 
 Crimson Trace is freakin awesome. I wanted to order an extra set of screws, I am a disabled vet and with hand issues, I sometimes strip screws. I wanted to order an extra set to have on hand just in case and CT sent me some and I was surprised that I was not billed for it. I will continue to buy lasers from CT without even a second thought.

Awesome laser, awesome company

Bought this laser and quickly installed it on my XD Mod 2 3.3 9mm pistol. Went on with no difficulties and was already zeroed. Took it to the range and it worked great. This is my 3rd CT laser (for different guns) and all have worked as described.

Works as described

With no apologies to Sig's LIMA365, CTC's LG-422 is "made" for the P365. Not only is the fit and finish outstanding, but the stippled relief on the Sig's grips is replicated on the Laserguard's side panels. Talk about attention to detail! Needless to say, the CTC Laserguard works flawlessly and it's hard to beat free batteries for life.

Perfect Complement to the P365

Love it. Easy to install, adjust and it has been rock solid.

LG-422G

I bought the Crimson Trace LG-422 laser instead of the Sig Lima365 because I saw that a lot of people are having trouble with the pressure switch on the Lima365. Sig just doesn't put out good quality products anymore like they did in years past. Crimson Trace seems to be maintaining their high standards and I'm very happy with this laser. It was very easy to install and zero and the battery can be changed without removing the laser from the pistol.
 
 I also considered the Veridian Reactor R5 Gen 2 laser but the instant-on feature doesn't sound as reliable to me as the pressure switch on the Crimson Trace and the on/off switch on the Veridian laser doesn't appear to be very easily accessible.
 
 One bonus (for me, anyway) is that Crossbreed is making some holsters for the P365/LG-422 combo.

Great Laser

This laser is a must have for the sig p365.
 It is very bright and helps with target acquisition.
 It looks great on the gun and fits the p290 holster.
 And dont forget batteries for life.

Very bright green laser

I received my SIG p365 Laserguard on March 23, 2019. It took me less than five (5) minutes to install. As with previously purchased Crimson Trace lasers, quick installation and a perfectly sighted product is the mark of this company. I highly recommend the LG-422G, over other SIG p365 lasers that are available on the market.

LG-422G Laserguard Green

Product did not fit my gun as advertised. I have an XDS Mod 2 9mm 33" single stack, the laser sight was less than a quarter of an inch too long, which is surprising since CS website says this will fit a 3" barrel. Otherwise, it seemed to work well, nice, bright laser; it just wouldn't fit my gun.

Did not fit as advertised

Bought this green laser right when it came out for my wife's S&W EZ 380 Auto she likes so much. This laser is easy to see in all light conditions, was easy to zero at 5 yards and works great for when perfect sight alignment isn't possible. I feel better that she has this on her pistol. Great product quality.

Great compliment to the S&W EZ 380 Auto

I received it today and it mounted very quickly and very snug...Great fit !.. The activation button is sensitive enough for any grip, for anyone. Went to the range and getting it zeroed was a breeze as with any crimson trace laserguard. The laser is extremely bright as you would expect ( zeroed in broad daylight ), and the on / off master switch made it very nice when I wanted to train with it off. Great Job Crimson Trace !!
