You thank them for the correction, log it in your memory for future reference... then you may choose to handle it in light of the new information or just continue on as if they hadn't said anything. If they protest, just say "I might do it that way next game, but for now... we are doing it this way." You are the DM... it's your game. Listen briefly to your players and if you make rules changes, try to keep them informed as it will likely affect how they will develop their characters.

I just carried half a dozen swords with me, took the Quickdraw feat, and life went on.
Funny though... as I write this... I wonder why none of the foes I fought ever dropped their weapons. I had to run around the room and collect my dropped weapons at the end of every fight. Why didn't any of the monsters drop theirs?
Anyways... my point is that even if the player is correct, it isn't worth disrupting the game. Ultimately... the DM is boss.
