It's hard to beat a 3" K frame. I've got two 3" 65-5 Ladysmiths, a 3" 65-3 that I carry for work, a 3" 13-3 and a 3" 64-3. At sone point I'll add a 3" 66 to my menagerie. In my opinion the 3" K round butt is the ideal plain clothes revolver.
This was an as-new M65-3 .357 heavy bull barrel acquired a few years ago. Less than one box of ammo thru it. Kept the original hammer, bobbed a NOS replacement, converted to DAO and added a proper grip.
