If in doubt, get the basic stainless steel M60 and put a Tyler grip adapter or a set of Pachmayr, Hogue, or Uncle Mike's (now Butler Creek)"rubber" grips on it, if it doesn't already come with these.
The very lightweight Scandium/Titanium guns will carry easier in a pocket, but recoil is BAD and the dull finish isn't as pretty as is conventional stainless steel. You can add one of these later, once you have become familiar with snubs generally.
All major grip makers can furnish nice wooden, ivory, etc. grips for snubs, as they do for larger guns. I personally think that Craig Speigel (Speigle?) has the most practical and lovely. He also designed the Butler Creek revolver grips, but his own are in wood.
The M36 is fine if you want blue, and many good used ones are around. But I'd get a late model stainless one, because they're certified for Plus P ammo and they don't rust easily when carried close to the body in humid weather.
