Steel lips are great (Butler Creek), but remeber that the receiver/trigger housing is aluminum. Fine if your gentle, but a concern over the VERY long haul.
The problem he was talking about is that if you keep slamming steel- lipped magazines into an aluminum receiver, the harder steel will damage the aluminum. Also, these two metals don't react well, so you shouldn't keep a magazine in at all times
