I figure I am like a bazillion other people that carry 124g and do most practice with 115g, I am sure you are set pretty well with 124g/124g. The only question would be if you might be slightly better off with the new fangled (just kidding, it is well established) 147g stuff, especially some of the new ones the FBI has somewhat motivated the continued development of.
IMO the free market is a great helper here, Speer and Hornady and the others are competing to sell ammo, so I am comfortable accepting that none of the major brands are going to leave themselves competitively venerable to any large degree. So I figure if I/you get some Gold Dot or HST you will be where ya need to be.
