  1. FIVE STARS!! Review by Steelhead08

    The absolute BEST "add-on" to this firearm platform your $$'s can buy; I purchased mine over five years ago and it's still going strong; as is my M&P full size .40S&W! The batteries last forever- even with well over 2K+ rounds fired in ALL conditions. A perfect fit, excellent customer support/service and, outstanding quality ... PERIOD. (Posted on 7/30/2019)

  2. On target on the Money Review by Smiley

    I Purchased The Laser For My S&W, M&P 45 Full Size, Only Came in one size the Large, I can see why that could be a issue for some But I actually use the large, It Fitted The firearm really well and the laser was Pretty much on target out of the Box, I Just was not impressed with the On/Off Button, it’s Recessed so deep it’s hard to turn off/on, I Understand it shouldn’t be too high, but needs some extra thought, But I Have 4 Crimson Laser’s, And You Can’t go Wrong With Crimsontrace, Great Product.

  3. Perfect Sight Review by Chris allen

    No sight alignment needed , point , get red dot on target and shoot. In a time when having to use your firearm counts, it's the best thing to have on your self defense firearm. No one every wishes to have to use your firearm but if you do, you'll be very glad you have a sight that is easy and accurate and on point.. Best product I have ever bought for a handgun..

  4. Bad ass Review by Luis

    Love the lg- 660, took 1 minute to install and eazy to use. Battery las a long time but i keep extra just incase. I use the midium size strap and this feels the same to me and regardless of what holster you ise it works no problem. Excellent product. Wish i had one just like it for my m400 ar. Thank you CT.

  5. Excellent in all ... Review by Dave

    attributes; battery life, fit, ease of use, etc. All deserve five stars IMO. Wishing a GREEN laser option was available! (Posted on 1/28/2017)

  6. Awesome product Review by Timothy

    After being unhappy with several other brands of laser sight, I purchased this one in 2013 for my brand new M&P 9.

    It was on target right out pf the box, and continues to be accurate to this day (4 years and 1000 rounds later). I never had to adjust it.

    The only maintenance has been replacing the batteries, which are sent to me free for life. I absolutely love this product. (Posted on 1/25/2017)

  7. Amazin Review by CFoster

    This laser grip for my Smith and Wesson is amazing! Especially helpful during low-light situations (Posted on 11/5/2016)

  8. Review by Tom Review by Tom

    As someone stated above, the only issue I have is I wish they made it for the variable sized backstraps(only comes in large), similar to the ones that come with the firearm. CT did show me another product that moves away from the backstrap unit. Haven't purchased the new one. (Posted on 7/23/2016)

  9. Great product, simple to install! Review by Art

    Only negative is too big for my hands! Need S&W small size. Broke unit trying to sand down smaller, will not turn on now! My fault, not CT.

  10. Won't leave home without it Review by Big Bill

    5 STARS. Easy to instal. A few minutes to adjust at range. Love how quickly I can acquire target. Love the rear activation switch, as soon as I draw from holster it lights up no need to remember where switch is. Also no problems with my holster interfering with sight. On off switch is recessed so no accidentally turning off at wrong time. Wish they made this for my PX4 Storm Beretta and my H&K VP9 , P30S and USP45 (Posted on 5/6/2015)

  11. Excellent Review by Gary

    When I bought my M&P, I bought a set of these grips at the same time. They are indeed excellent. The only thing I could ask for is a variable sized backstrap, similar to the ones that come with the firearm. Luckily for me, these are the perfect size, so no loss there. (Posted on 4/10/2015)

  12. Great Product Review by GoinHot

    Could not ask for more. Installation was a snap, did not even need to adjust the laser - POA/POI right on. The fit is perfect. Thank you CT! (Posted on 3/30/2015)

  13. Great for any situation Review by Keith

    Found this laser grip to find the quick sighting in any situation from conceal carry to every day duty. Free batteries for life is also a plus. I recommend this product to anyone who needs help sighting in targets. I also bought the light guard and now I have the best of both worlds. (Posted on 1/20/2015)

  14. An excellent addition Review by DrkKght03

    This was my first Crimson Trace product and won't be my last. It's almost inconspicuous when looking at the handgun, but when you simply grasp the firearm, it's on and ready. Of the two holsters I have for my handgun, the Crimson Trace laserguard is not affected by either when holstered. An excellent addition! (Posted on 12/25/2014)

  15. Last Laser I'll Ever Buy. Review by Terry

    This was a simple grip to install and I had to make a mod to my pistol due to ambidextrous safety and still only took a few minutes to install. The quality is excellent and I don't have to worry about if the cheap lasers I've purchased in the past will work when I attempt to use them......they've been replaced by a good quality product.

    (Posted on 11/4/2014)


    I bought the grips for my S&W M&P 45 Simple to install as easy as changing the grips. Easy to sight in, and not needing to think about turning it on, just pull and point and your ont target, that is awesome! My wife want grips for her Ruger SR9c now. The grips are worth the money! (Posted on 9/16/2014)

  17. Ambidexterous safety, an easy install Review by Mark

    My local gunsmith just cut the RH safety off of my M&P .45 auto. and checked with S&W to insure it was OK. It was and the handgun fits like a glove in my hand. Point the red dot of the Laser and that's where the bullet will go. The very best quality in my opinion. I also have two lightweight S&W 38+P revolvers and they also work dependably.

  18. Rock solid sight Review by Bill Sansom

    Took a little bit to get the old grip off my S&W.40M&P. But, after actually reading CTC installation instructions, the LG-660 was up and working in about 5 minutes. Out to the range and fired 150 rounds, fined tuned the LG-660 for 15 feet, and using only the red dot, not pistol sights, I hit dead on wherever the laser pointed. The LG-660 did not "recoil" off alignment, and the bright red laser dot showed up bright even in bright sunshine, and against a red bullseye on my target. In low light conditions, even darkness, the red laser is spot on hitting target at 50 plus feet. I believe this is the best laser sight on the market. (Posted on 1/20/2014)

  19. On the mark from day one Review by recongunny

    Received this as Christmas gift, took it out to the range the next day and found out it was perfectly zeroed in on the first shot. I was totally amazed. I have fired approx. 300 rounds and my S&W is still on the mark. Wish I had one when I was in Nam. (Posted on 1/13/2014)

  20. Thumb safety Review by BD

    You can not use this grip on a M&P with abedextrios thum safety's. otherwise I would have it on this gun (Posted on 7/23/2013)

  21. Outstanding addition for your M&P - A Must Have Item! Review by Greyfoxvt

    All I can say is Very Nice... The S&W M&P is a great handgun, and althought I thought it was the complete package, I had no idea I could bring it up even further by adding the Crimson Trace Lasergrip. Right out of the box I was hitting 50ft targets with a grouping the size of a silver dollar. It was easy to install, and even easier to get used to and use. The stylish grip makes it just like the factory choices you have, but it just seems to fit my hand perfectly. One turned on, just gripping the pistol activates the laser, and it is easy to see within reasonable ranges of use. The best thing is it still fits in the factory holster without a problem or modification. This is a must have for all M&P owners to complete your setup. Thank you CT! (Posted on 5/31/2013)

  22. Awesome sight!! Review by short-fuse

    Purchased mine at the N.R.A. convention in Pittsburg. Right on target out of the box, quality product, as are all my C.T. laser grips.. (Posted on 4/26/2013)

  23. Great product! Review by Jimmie

    I carry a Smith & Wesson M&P .45 every day. During work hours it has a light attached, the light is removed for easier concealment when off-duty. I like that the laser sight is always with my weapon, not sitting on the shelf with my light like some of my coworkers.

  24. 5 Stars + Review by steelhead08

    Received my Lg 660 for my spank'n-new S&W MP .40; in summary, AMAZED! Definitely near[or as close as you're going to get to]military grade quality,power,user-friendliness,etc I am a retired US ARMY Vet. from a specialized 18B MOS-I KNOW what I'm typing about.. I HIGHLY recommend this product. Quite simply put: you DO get what you pay for. (Posted on 9/24/2012)

  25. Greatest thing since sliced bread! Review by Bernie

    I am absolutely sold on this laser sight. It hits where it points, everytime.... I can't imagine an intruder who sees this sight on him who will NOT turn and run. It has to be the greatest intimidator of all time.....Now where is the GREEN one so I can see it in bright light? (Posted on 4/16/2012)

  26. Wish it came in the large backstrap size Review by starlifter

    Very good funtionally. I shoot much better with the factory large backstrap. Haven't adapted to the medium size. If I grip the gun normally, my index finger contacts the trigger between the first and second joint. When I transition from indexing on the side of the frame to inside the trigger guard, the trigger guard is in the way for a smooth transtion. If I roll my hand in for trigger finger alignment, trigger control suffers. I'm 5'8" with average size hands and fingers. I can't imagine how the big guys manage. I would have been much happier if this product was available in the large size. (Posted on 2/12/2012)

  27. I HAVE A M&P 40CAL Review by David R.

    i AM SAVEING UP FOR BY NEXT SET OF SIGHTS FOR MY S&W 910. (Posted on 1/29/2012)

  28. User-friendly in every way Review by Euromutt

    Easy to install, easy to use, goes through batteries very slowly, and was zeroed perfectly out of the box. There's almost nothing not to like about these grips, and I have them on both my full-size M&P (my "nightstand gun") and my Compact M&P (my carry weapon). The only quibble, and it's a minor one, is that if you're left-handed (as I am), it's next to impossible to find an IWB holster you can use, because the sweat guard interferes with the laser housing. (Posted on 12/30/2011)

  29. Year on duty and going strong! Review by Devin Wulle

    I have had the Crimson Trace LG-660 on my M&P duty weapon for a year now. Rain or shine, hot or cold. It works and no matter hard I knock it around it keeps on ticking!

    The 660 is slightly larger than the "medium" M&P grip panel, but smaller than the "large." I like the medium grip, but I have quickly adapted to the size of the 660.

    The LG-660 is easily strippled (textured) by a gunsmith (This would probably void the warranty) If that is your preference. I had this done to mine before I even installed it.

    So far battery life is awesome, I used the original batteries for a year and changed them recently just in case.

    One thing I have learned using the lasergrip is that you can place your finger along the slide if you want the laser to be covered up (without shifting your grip and turning it off) or put your finger at the ready along the frame to have the laser pointing at the target. I could go on about how fast I can get hits on target, but for the virtues of lasers in general see the videos that CT has made. (Posted on 12/13/2011)

  30. Awesome Review by Shwampthing

    If I could afford it they would be on all my hand guns
    You don have to think about anything, you grab your gun the laser comes on. (Posted on 12/11/2011)
