I own a S&W 686 4" with a hammer mounted firing pin.
Does anyone know when S&W changed to the current configuration?

The 686-2 engineering change to the frame mounted firing pin was done in 1987 according to the Standard Catalog of S&W.

1987?!
It was sometime after the year 2000 with the 686-6 model I believe.
I have a 686-2 and I bought it for the hammer mounted firing pin among other things. My pistol was manufactured in the early first quarter of 1988.

Be aware that Smith & Wesson serial numbers frames and then builds them into guns later. Guns may also remain with a distributor or dealer for some time. It is not unusual to discover that a gun you recently bought was actually made some time before.
The 686-2 change in 1987 changed the hammer nose, bushing and associated parts. (frame mounted firing pin? this is not clearly stated)
The 686-5 change in 1997 changed to MIN hammer, trigger and floating firing pin.
The 686-6 change in 2001 was for the internal hammer and trigger key lock.

The Old Fuff is going by memory, which isn't always the best... 
But anyway, S&W had a recall on the early *86 models that I believe included replacing the hammer nose (firing pin) and bushing. The "-2" reflected this modification in regular production.
The "-5" was when they changed the lockwork to MIM parts, and that included frame-mounted firing pins. So far as I know, none of the MIM hammers had firing pins mounted in them. In some models they incorporated MIM triggers before changing the hammers. You can tell a MIM trigger because the back of the fingerpiece is hollowed out.
