If you want a slick laser that turns on just by picking up the gun, this is the product for you! I would have preferred the accuracy of the laser that goes into the guide spring, but that doesn't turn on when you pick up the gun, so this is the way to go for personal protection.
Pros: bright, turns on when you pick up your gun, easy setup
Cons: Expensive, Not in line with the barrel
