Your shrouded ejector indicates a 1972 or later gun. It's rated for about 3,000 rounds of +p, unlike my 1968 unshrouded which is not. I'd still stick with standard pressure, but your gun should be okay with +p as a carry load.
As for me, I practice with 130-grain Winchester White Box standard pressure, and I carry standard pressure 158-grain Buffalo Bore LSWCHPs, as well as only dry firing with A-Zoom snap caps.
Welcome to the club, it's a pretty great one I'm very new to myself.
