My 15-4 is one of my most favorite handguns I own. I found it (luckily) at my local shop, in the original box, all manuals, papers, tools, etc. Looked to me like it had not been fired (was not labeled as NIB, just looked like it was). Really in perfect condition. I paid $225 for it (about 10 years ago) and I could not be happier. It has the factory target trigger and hammer installed and is the most accurate handgun I own.
