Well, if U want a CCW weapon, it is great. I do not believe it is a good gun to introduce someone to shooting, though. Those tiny guns are usually a blowback design - so they will have more recoil than you would think. Plus, their small size magnifies this.
Most 380s (yes, I know it is a 32 we are talking about) have more recoil than a 9mm, because most are a blowback design. There is no extractor like the 9mms guns. Most people would assume the smaller caliber has less recoil, but it isn't always true.
I am thinking of even small 9mms - like a Glock 26 or Walther compact. I do not think any of these tiny guns, while terrific for concealed carry, are good to introduce someone to pistol shooting - not if you really expect to the person to like it and get into it further. Chances are, this will make them less interested.
I think the Berettah Cheetah 380 would be a decent, smaller gun, to introduce someone into pistol shooting. It is a blowback design, but is still a fair size. A Ruger 9mm semi auto, a CZ or a Taurus 92 would be great, fairly inexpensive, 9mm pistols that would be great learning tools that do not cost too much money. Of course, these are larger guns, though.
U can get a Ruger for around $300 - not much more than that Beretta Tomcat.
Getting back to only the Tomcat, though. As I said, I would not buy a used one, personally. If you MUST, shoot it first before purchasing - ask him to meet at a local range - be prepared to cover the ammo cost and your fee, and insist that you get to try it first.
