I don't think it is misplaced. It's all about what you want to do. I've been consolidating my guns into less calibers and more popular calibers. You are absolutely correct about finding ammo. The problem with finding 10mm ammo is that in normal times, finding ammo is on a different level than finding it for the 40. Other than ammo availability, diversity of platforms and the ability to fit into a 9mm size weapon, the .40 is inferior in every way to the 10. Still, in normal times, all Wal Mart's carry .40 S&W and none (around here anyway) carry the 10. In today's times, the .40 is indeed hard to come by. The problem is, most gunshops charge full retail and a lot of them are charging significantly over that right now. Wal Mart and a few others are still charging pre-Obama prices. The 40 is in short supply due to its very popularity. The 10 is on the shelves because few shoot it in the first place.
