I’ve been using a Smith & Wesson Model 637 for sometime now and it has a Crimson Trace Laser on it that in the almost 4yrs I’ve had it, is still on the first battery that came with it.   There are pros and cons to each laser design, whether it attaches to the trigger guard, the rail system, or is fired from the grip.   With all of my experience, hits are what count and even shooting long range, I’m hitting steel plates and not so concerned about MOA.  Getting the first hits is more important that group size and in my opinion, lasers are excellent pointing devices and people should be less concerned about trying to hold the laser perfectly still and putting every bullet in the exact same hole.

After reviewing several self defense engagements,  I noticed that every one of them was at night or in very low light conditions.   There’s a reason most handgun manufacturers have rails systems on them now, Glock, Sig, Springfield, Smith & Wesson because flashlights and lasers are very durable and are almost considered standard.  There is always a certain amount of training and time you should have with a device to gain the muscle memory to deploy it properly but when I think of laser grips, it’s always Crimson Trace Laser Grips due to their time in the industry, warranties and reputation.  Night Sights have come a long way and might cost about half of what a laser sighting system might be but lasers have their own illumination factor similar to what flashlights do and can “light up” a target in dark situations.  Just something to consider when shopping.
