I've had two Ruger convertibles over the years. IMHO, the 9MM/.357 is one of those ideas that really looks good on paper but doesn't work out all that well in practice.
When MilSurp 9MM was available dirt cheap, I used a lot of it in Rugers for informal, short range plinking, but it loses accuracy fast past about 15 yards. (At least, both of my guns did)
For pure Accuracy, my best results came with 148 gr hollow base full wadcutters, loaded in .357 cases over 3.2-3.5 grains of Bullseye.
My best all around load in these weapons was a Lyman 168 grain (linotype) cast (358-429??) over a MAX charge of H-110.
Surprisingly, my most accurate jacketed bullet load was the Remington 125 GR. JHP, again over a max charge of H110.
History fails to record a single precedent in which nations subject to moral decay have not passed into political and economic decline. There has been either a spiritual awakening to overcome the moral lapse, or a progressive deterioration leading to ultimate national disaster.
If you think a strong military is expensive, think about what a weak one would cost
