Been using Herrett National Stocks for eons. Target grip. Bought 'em at a gun show for $20Cdn, then. $78US now. Very similar to the Baikal grip.
"...do not fit me very well being right handed..." You'd think Smith would put decent grips on a $1,100 pistol. Didn't pay that much for mine. Mind you, I've had it for eons too.
