I have a love/hate relationship with them. I was a staunch 1911 guy for many years but now own a Gen 4 Glock 19, a .9mm Shield, a CZ P10C along with two other CZ's that are hammer fired. I have put more rounds through my Glock 19 than almost all the others combined. I do not like the finger grooves and I would prefer a Gen 5 for the ambi slide lock/slide release but the darn thing just performs and performs well. I don't even mind the looks.
