Also for those who experience a slight creep in the single action pull, here's a little trick that will usually fix it if it's not too bad.
MAKE SURE THE PISTOL IS UNLOADED !!!! Cock the hammer and dry fire the pistol while putting heavy pressure on the back of the hammer with your support hand thumb (like your trying to push the hammer forward to make it fire). Usually 1 to 12 times will result in an improvement in the single action pull. Basically what your doing is accelerating wear on the hammer/sear engagement surfaces and ironing out any minor surface finish imperfections.
