Question: Is this item the CTC LG-308 product?  It's a square-butted grip to fit the round-butted L/K frame S&W's such as the 686-Plus, yes?
Document: This laser grip fit my S&W 686 perfectly. I am a long time user of Crimson Trace products. This is my fourth unit and very satisfied. This laser grip is a must have for any revolver pistol.
this grip is amazing I just love it! put on a s&w governor. fit is good and lazer is awesome.
I ordered this through Amazon website, but the order was actually fulfilled through Gun Holsters Unlimited...for less than Amazon LLC was charging for the same item. I am very happy with my purchase. The Crimson Trace grips I ordered for my S&W Governor arrived a couple of days earlier than expected, which was a nice bonus.
This produce came in the original container supplies by Crimson Trace and worked exactly as advertised. It was the perfect fit for my S&W Governor model pistol. It was brand new, not a used piece, and has performed as well as expected. The only shortcoming to the purchase was that I still had to inquire from Smith & Wesson, as well as Crimson Trace, about exactly what model laser sight would mount correctly to my handgun.
Crimson Trace, always reliable. These fit easily and were a great purchase for a home safety firearm. Accurate out of the box, minimal adjustments.
This is my third Crimson Trace set of grips, and have always been completely satisfied with their products. Best laser grips on the market.
Sighting is fine...I have not had to adjust it at all after testing at my local gun range. I feel confident that if my alarm wakes me up in the middle of the night, I will have the advantage of not having to line up the rear sights in the dark and will be able to defend my home.
Making sure you know exactly what model tool fits what model pistol is a good habit to get into.
I already owned several other Crimson Trace Lasergrips before buying these and all perform perfectly. The reason I install lasergrips on my pistols is because of the extra edge they offer, should you ever be in a critical situation and need to get on target quickly. Always practice at the range with your pistol's sights so that you are proficient without relying only on the lasers. I also found out firsthand that Crimson Trace stands behind their warranty when I had a problem with an old set.
