I agree, she almost certainly means the 3913.
If so, it is a decent gun, very reliable, but the ergonomics are not that great for most people. If it fits your hand, go for it. S&W gen-3 semi-autos are the Dodge Darts of the handgun world; uninspired, and somewhat clunky looking, but they work just fine.
if you were talking about a 1913, my bad.
