JayG takes his newly acquired lightsabers lasers out for a spin and has an astute observation
One thing that jumped out at me as I was shooting with the laser sights was that it wasn't a panacea for shooting issues. I had expected to sight the laser in on the X-ring, then be able to chew out the X with boring precision. It doesn't work that way at all - things like smooth trigger control, sight picture, etc. are still important and can still wreak havoc with your shooting even with a laser sight. The laser sight does make acquiring the target in a faster manner easier, that's for certain; it does not guarantee a bullseye.
Bingo. One thing that I have failed to mention in detail when discussing my lasers on my pistols is that it doesn't do a damn bit of good for your shooting. What it does is gets your pistol on the bullseye faster (I have the same experience with my red dot on the Ruger). When you anticipate the recoil, the laser is simply going to show you exactly that – anticipation via a very wobbly dot. Your shot will still go exactly where you aimed it wherever that dot happened to be at the time the hammer fell.
This is why I think lasers make a fantastic training aid. Instantly you can see what's going wrong with your form / shot / breathing / etc. I suffer from bad breathing control so my shots end up in a vertical line. When I turn on my laser, it's pretty apparent that the dot is going up and down. It's also good for dry firing practice to see if you're jerking the gun when you pull the trigger (and is very effective when live firing and you get a jam / misfire and watch the dot jump around like a Jack Russell terrier).
I highly recommend a laser for your handgun. Even if you only use them for training, they provide an excellent tool for the gunny looking to improve his or her shooting.
