In general 7-rds mags are interchangeable between true 1911 clones which your Remington is. 8-rd mags usually work too if they are of good quality. Larger capacity mags tend to be double stack and need a Para Ordinance style large magwell. Now there are long single stack mags that extend outside the standard magwell. Good ones should work but I've never tried them for functionality. Hopefully someone else who has will advise you...
