Sharpshooter
Do you reload ammo? If not, the 10mm will be expensive to feed when you can find ammo for it. If you do, 10mm can be a whole lot of fun to reload for. I have a couple of 10mm pistols and really like the round. The Glock G20 is one of the most powerful handguns around and packs over 10,000 ft lbs of energy per magazine. But, if you don't reload or if you don't own a .45, I'd probably recommend going for the .45. Everyone should own at least one .45. Preferably in a 1911. It's tough to get a more American semi-auto than the 1911 in .45.
Words of wisdom.
