I'm sitting at 60x AR mags, and over 20x for each pistol.Agreed. I Changed gears from, "I have X number of mags for X type and caliber" for personal use in a particular session... to... "I need X number of mags PER each specific firearm". Realizing that they will eventually be passed along as "singles" to the various children or grandchldren.
Example: 20 AR mags is just fine for me to go out and do a shooting session, and maybe shooting multiple AR's, but my children or grandchildren inheriting one of grandpap's old rifles with only 2 mags per rifle just wasn't going to cut it.
