I'm no expert, but I think several companies offer the bar-dot config. I personally have the Ashley Express vertical bar rear/ big dot front (if that's what you mean ) on my G30. Many, including me, would recommend Wolff +10% mag springs in a G30 if you're shooting 165 or 185 grainers or any wide-mouth HPs, to prevent low jams, which a number of people (including me) have had problems with. Also, though I'm the only one in the universe who thinks this, I like the mag release spring to be extra power also, to prevent accidental mag releases during daily CCW wear - I had mine smithed for this feature. I also like my Pacmayr slip-on grips.
