Thanks for reaching out sir! For training with a 1911, I prefer an FMJ round nose cartridge loaded to a muzzle velocity as close to 830 fps as possible. I believe you'll be happy with Federal American Eagle, Minnesotan ammo which is pretty much a staple at American ranges:

Sellier & Bellot of the Czech Republic is also pretty darn good if you'd like to save a few bucks:
