I used to buy the whole no lock thing. I just think it's a tempest in a teapot now. Chance of ever having to use a gun in a self-defense situation in your life - next to nothing. Chance that at that very same moment you would experience a rare malfunction - closer to next to nothing. Jamming of a semi-auto happens more frequently than failure of an S&W IL, yet I don't see hysteria about it. I prefer them without the lock, but the lock is there to stay, so if a new model comes along that I like that has the lock, I'm not going to refuse to buy it for that reason alone. Everybody has to do their own thing though.
