I have used both Federal Arms and Bar Sto not in the G23 but in a G 22. The Fa was a ported version. REcoil was arrested but I don't really like ported barrels. If you do, this is the among the best I have tested.
As might be expected the Bar Sto barrel gave gilt edged accuracy and excellent function, yet it was a drop in. With Federal's 125 grain JHP, accuracy was better than I had ever obtained with the .40 and premium ammunition. The gun worked well with either barrel. Lead bullet loads, with hard cast LaserCast bullets, worked great.
The Bar Sto is el premium. One group measured 1.25 inches at 75 feet off a careful rest. My gun has Aro Tek night sights, similar to NOvak.
Also have had good luck with lead bullets and conventionally rifled barrel for G22 in .40, from Jarvis. But it was fitted. Fitting reduced slop and wear.
Hope this helps.
