Crimson Trace grips suck, why????? Cause they don't accommodate left handed people, my hand placement of thumb on top of thumb blocks the laser path. Great for righties though.
I bought the Uni-Max system by Lasermax, it's thin and attaches the the dust cover rail on my handgun. Works great, just not during the day when at the range.
It's more for night-time home defense, which of course you cannot do if a crook breaks in, I could just imagine what the prosecution would say, " so you installed a laser on your gun to make killing easier?", know imagine if you happen to have hollow points in the gun along with a laser? The anti's would have a field day with your "handheld death machine".
