semi auto for a lady

[rambler]

My wife wants a handgun.

I had my heart set on a S&W Model 60...but she won't have a handgun without a real safety, so I'm trying to find a reliable semi auto that has a safety - not just a trigger safety like the 1911's but something that will decock and render the gun harmless until the mechanism is reversed. Does anyone know of such a creature?

The only thing I'm sure of caliber wise is nothing smaller than .380 - unless yall would recommend 22 magnum or something like that.

Thanks for your help.
