according to the owners manual mine came with, the R1 uses a Series 80 style system.
most 1911's do have some amount of play in the trigger, just due to it's design.
but to be on the safe side, you might have a competent gunsmith check it out to make sure it's not an excessive amount of play in it. if it does, send it back to Remington for warranty repair.
