Welcome!It depends on your intended use for the gun. For a beginner who is just shooting at the range, a .22 is the best choice, probably followed by an adjustable-sighted .38 or .357 revolver. The latter can double as a fine defense gun, and if you choose the .357, an outdoorsman's gun as well.I am not quite sure what kind of gun I should be looking at. I have been looking around and heard lots of good things about glock and the glock 19 caught my eye. I have read in a few places that a 9mm is a good gun to start out with. Is this true?
9mm pistols are great for defense and some limited types of competition (www.idpa.com). Of the full-sized autoloaders, I think 9mm is the best pace to start, if you must buy a fighting gun right off the bat. Glocks are fine pistols, and are my preference, but there are many good pistols out there.
I will leave the questions on MS law to someone who lives there.
