It's not hard to do! I did that at a match about 10 years ago. I have several cordura packs that hold 6 mags each, to keep things organized, except a pack of Ruger mags doesn't work very well for a Sig! Thankfully it was one of the few close matches and I just barely had time to run home and grab the other mag pack. I learned my lesson, I now have a check list I go through before I leave.one can never be too prepared.
But as for mags, how's this. I went to range today. Opened my new safe in preparation. Ah, nice, 3 fully loaded mags. Threw them in my range bag. Get to range, slap a mag in my 43x and it falls right out. Yep, they are for my new gun I've yet to take delivery of. Not exactly Glock mags.
