Holy Lazarus post !
Funny thing is I hated SW 3rd gens when they were new (mostly because of the ugly Delrin monogrip),
Back in those days I carried a SW 39-2 or a Model 59.
When SW went to polymer frames I found a new appreciation for 3rd gens.
My current daily CCW is a Model 3953 (although I honestly have no love for the dao trigger).
Also have a 6906 but top of the heap is my PC9 Performance center gun with factory Briley barrel bushing, although it is based on the 6906 it is a custom built and hand fit masterpiece from the days when the SW Performance center was just that.

Ps , also have an HK P7, if it weren't LNIB condition and worth so much $$$ I would carry it instead of the 3953, IIRC even new they were very expensive.
