S&W 952 vs. 952-1

[plnkr1234]

Hi Guys,

Thanks for responding to my price check thread a few days ago. I've had my eye on what I thought was a 952. Today while looking and drooling over it, I noticed that it was actually a 952-1 with a Wilson Combat adjustable sight and no large rollmark.

Does anyone know the difference between the 952 and 952-1 if any? Also, is one worth more than the other?

Thanks
