The revolver pictured is a model 327. It is an 8 shot, scandium framed, titanium cylinder, 357 Magnum revolver that was introduced around 2003 or 2004.
This compact N-frame revolver weighs in at 24 ounces and packs LOTS of punch.
The revolvers commonly referred to simply as 625-10 and 625-11 are Scandium framed, stainless cylinder, 8 shot 45 revolvers. I have two of them in 45 Colt.
