Bladetech or Comptech holster
Not a fan of the RHT holsters both I've had the guns rocked in the holster (i.e not due to the attachment, poor fitment of holster to gun)
On some type of brkt (boss type for adjustment)
I like CR speed pouches with the 1911 insert because they keep a mags a little bit away from my body (overweight)
Good belt, DAA, CR speed, Shooter Connection belts are great for the price.
Practice, dryfire, live fire, repeat
