RE: Is the 10mm auto here to stay? Or fading away?
It will always have a cult following. It is actually quite popular here in alaska, you can even buy ammo for it at walmart and most sporting goods stores. I have a custom 1911 in 10mm that I used for bowling pins and a backup gun while hunting. I have also carried it a few times for concealed carry, its tough to conceal with its 6" comp barrel, but having 4, 15 round mags is a lot of firepower if you need it. I think it is about the best auto handgun caliber for hunting/self defence. I think part of the over penetration problem was due to the FBI wanting to be able to shoot thru a car as one of their criteria. Penetration often went hand in hand with a calibers ability to put a subject down right away. Its also great for deer, black bear, and any other medium sized game. Its too good a round to completly die out.
