Spotteddog and dbc, yes to both questions.

For carry pick a quality modern bullet that works in your gun (reliability is first) and is accurate. Any of the current HST, Ranger-T and Gold Dots in 9mm will work fine for defensive use, as will the Cor Bon DPX.

For practice I use whatever I can find cheap that won't blow my gun up, which normally means "generic" boxed US factory stuff since I don't reload. I have found WWB, CCI Blazer and Lawman, Federal AE to all work fine.
I don't even worry about bullet weight in practice ammo unless I am shooting a match. 115-147gr runs my guns just fine, and POA vs POI with a 9mm out to the 25 yard line is so close that I quit worrying about it 20 years ago.
