Np thats a clean looking glock im a fan....i have a 19x i love it! These glocks will eat any ammo you put in them steal case or brass . Thats why i like them.
Lasers are pointless and give bad shooters a false sense that the bullet will actually hit where its pointed. Just train and you wont need a laser that is guaranteed to lose its zero.
Know your laser/gun and keep it zeroed and it’s not hurting anything but adding a little size. Helps you quickly get on target at least in an emergency, especially in low light conditions; can be more helpful than a flashlight in certain situations.
