Default Laser sight on my 640

Got my new SW640 2" barrel some months ago. I definitley was not having fun with this gun, seems I couldnt hit the barn door, nor the barn it was attached to. Its the only pistol Ive ever owned and I knew I would need to shoot better if i was going to keep this little weapon. Thanks to some here on this board for advising well on a Crimson Laser sight. I chose the LG405 which was easy to install.

The first thing I noticed was that the new grip was considerably shorter than the factory grip. A full pinky finger shorter. I really liked having that full size factory grip as there is some extra comfort knowing my full hand is wrapped around the weapon.

Then I was off to the range, shot a full box (50) of 38sp+ and I really had fun shooting the 640 with the laser sight. My shooting had improved considerably over the open iron sights from the factory. At 5 yards hit every shot within a 9" paper plate. I dont think thats very good shooting but it is a vast improvement. At 10 to 20 yards I could hit a target the size of "somebody". Again, not very impressive accuracy but its an improvement. What I found very useful with the laser was that every movement of the gun could be followed by watching the laser dot. When I pulled the trigger the dot would move in a certain direction, sometimes a considerable amount, depending on how careless or fatigued my hand was. It also showed how a smooth trigger pull could improve my accuracy. But I doubt a smooth trigger pull will be of any concern if I ever need this gun in a real fight.

I was also impressed with how the laser didnt need adjusting after I installed it. It was already zeroed in and it did come with adjustment tools incase its ever out of whack. The big drawback was that on a bright sunny day the laser dot is just plain hard to see beyond 5 yards.

I found that to be one of the biggest benefits of lasergrips--they're great training aids. A useful exercise is to spend some time dry-firing the weapon repeatedly while trying to keep the dot on something very small (a doorknob across the room, for example). It's difficult at first, but the immediate feedback helps you learn quickly how to control the gun for best accuracy.

Here's my 640 with the same lasergrips as yours. They made a great revolver even better!

I have Crimson Trace on a Ruger LCP, but have yet to give them a go on a revolver. Been thinking about it quite a bit though...
