I recently picked up a 686 plus.  Really digging the gun except for two things, the lock and the grip.  

I took care of the lock and now I am looking for a replacement grip.  I don't want one with finger grooves.  Also, I wear a medium glove but can squeeze into a small.  So far I have been eyeballing the Altamont target grips in rosewood.  No finger grooves and the price seems good.  Just not too sure on the size.  

Any help would be appreciated.  Oh, this is a newer model with the round butt.
