686-6 ....is a 2001 gun ../..in 2002, they went to the 686-7's engineering revision...
In the catalog it'll be referred to as an 8 3/8" barrel..., L frame and the 686 model is still in production in a number of variations.
They're solid guns....they shoot great ...the extra weight is a plus.../ the 4" and 6" guns are a little more popular in my area - especially the 4".
With the change to the 686-5's in 1997 ...S&W changed the gun to include MIM hammer and the floating firing pin, MIM triggers and the Internal Frame Lock....so S&W collectors are not too keen on this model as of 1997 and beyond. But even though collectors aren't too excited about them - doesn't mean they aren't solid guns.
