RE: 5'9'' - 125lbs lady needs a 9mm?
Thing I don't like about S&W9mm's, is that they aren't safe guns at all, my grandpa has one, and it's safety is the hammer, mainly, but when you chamber with the slide, the hammer is automatically cocked, and if you pull the trigger, it'll go off, it really isn't a safe gun, and that's one reason I really don't care too much for pistols, I like revolvers better, IMO, but I have only fired 2 semi-auto pistols, a 40 S&W sub-compact millenium edition, and my grandpa's 9mm.
From what I hear about the Glocks, the safety is the trigger, which I think might be dangerous, but then again, maybe when it comes to pistols, I'm paranoid, but better paranoid than dead from a gun accident, I just don't like the idea of the holster pointing the gun at my kidney, or worse, diaphram, just don't like it. Maybe a boot holster is more safe.
Sorry for thinking out loud.
