For some people on a tight budget or a complete newbie, one gun is what they need. It's better to completely learn and train and become very proficient with one gun than trying to learn a Glock 26 and a 1911 at the same time. It's a better way to start IMHO.
...It's hard to go wrong with a 4 inch Smith in .357 magnum for a "one gun to do most" philosophy
With all do respect to the fanboys, this is the best answer.
Good for hunting, range and self defense.
The versatility of the 38/357 platform is the best choice.
Good call on the .357 magnum 4 inch as viable option. HOWEVER, "clinton and Wesson" will never find itself in my collection.
