I agree with everyone else, the .38 will do just fine. However, as also mentioned, velocity from a 2" barrel is not that great. A bullet that mushrooms before it gets adequate penetration will not serve you well. You need to reach vital organs to be effective. So in any pocket pistol, be it a .38, 9x18 (Mak), or .380, etc., go with a SWC, or even FMJ. Deep holes come first, expansion comes second.
