I have an appreciation for older pistols, single stack 9mm are overlooked by so many who feel that half a box of ammo needs to fit into the gun to be useful for anything. I would like to find a nice and clean early model 39 sometime, S&W really got it right with the grip ergos on that one.
Here is a photo of one of my 9mm single stackers...
