Well, size-wise, the Star S has a longer bbl., so velocity will be higher than for their DKS or other smaller .380's, and they do feel so great in the hand, and they're probably lighter than most small 9mm's, and thinner. They're also just plain cute, and all steel. And they usually sell for a modest sum, compared to a new Beretta M85, etc.
I like the exposed hammer.
Years ago, I asked George Nonte, then a leading gun scribe with a penchant for autos, if he thought the Star would match the Beretta M34 for reliability, and he thought it would. Probably, feeding JHP's depends on the gun and the brand.
