Let me go ahead and "dictate" to a newbie. For a newbie who is looking for a utility weapon for a range of self defense including conceal carry and home defense... I always recommend the following:
.357 hammerless, DAO, 2" barrel (Snubby) revolver. It can be loaded with .38s, it is easy to conceal, it will never jamb (limp wristing), if one doesn't shoot, squeeze again, no hammer won't catch on draw, DAO (Double action only) makes for a long strong trigger pull, easy to train on, easy maintenance and best reliability (comparatively and generally speaking).
..with a laser on the grip...
