Got the C-T laser grip for my Kel-Tec P3AT and love it. Here's some observations: First, and I've not seen this concept posted... When you use a laser sight you are seeing where the MUZZLE is aiming. The red dot moves, but the target is still (visually). When you use iron sights, even the very best, the TARGET is what is visually seen as moving. This is key to training the eye and the sighting/grip/hold/stance. So when you are practicing, even with a dry fire/snap cap with laser you are actually improving your ability because of the intense FEEDBACK. You know when you are squeezing and pulling off target (or not) in an indelible way - you SEE it while it happens. This is key for feedback to work. Again, the key factor with a laser is you see the aim point moving not the target (visually). With iron sights it's the target which appears to move around - very low feedback and skill transfer. So what happened is, I shot one magazine with the laser then moved to my S&W 9mm and guess what? May aim and steady holding had ALSO improved with the non-laser iron sighted S&W. It improved quite markedly. There was a definite and obvious immediate skill transfer. Now this effect may not stay with me, but it was startling. I put all 12 rounds into the target's center of head at 30 feet, several in the same hole. I usually am not this accurate with the S&W. Wonder if anyone else had experienced this 'effect'?
