I have a magazine disconnect on my 4506-1. Civilian concealed carry is non-existent in New Jersey, so if it’s the pistol that I keep for home protection, I have to unload it, and the magazines, before taking it to the range. Considering that I load/unload the weapon at least 4 times a year, that feature, and the safety de-cocker, add a level of functional protection that I feel comfortable with.
