Laser grips? Are they any different now?
Just like the white lights that could only be mounted to trigger guards and the lasers that mounted the same way, gun manufacturers have been modifying their firearms so that can all be accessorized. It’s really easy to spot some of the older model Sig 228 and Sig 229 guns because they don’t have rails. Now it’s pretty much the law of the land to have a rail on your handgun because so many understand the need for using a white light. Just like everything that has to do with firearms and caliber debates, you have to know what the task at hand is and know what tools will work to get the job done.
I agree that the best place to put a laser is probable right inside the barrel and beam it out of the exact same spot the bullet flies out of, but right now that is impossible. Lasermax and Crimson Trace laser grips have different approaches to getting the same job done, and it’s really what your preference is. For close up fighting, once you get your laser setup for the ranges you wish to do combat training or defensive training in your laser will work, but side mounted lasers will become inaccurate once you get out of your comfort zone.
