Re: 400 CorBon...
It's not that the .45 was ever not enough for me, but I picked up a .400 Corbon barrel for my 1911, along with a set of dies about 3.5 years ago. I had to pick up another barrel bushing and a link. It wasn't a drop in either. Once I got it all fitted, necked down and TRIMMED some brass, loaded it and shot it, I was happy with it. It doesn't have anything that the 10mm doesn't, just a shorter length. Listen to bohem and get a 10mm. Ammo is more readily available for a 10mm(relatively anyway). Sometimes I just buy shit because it's for sale....
I did end up with a .460 Rowland barrel as well but that's a whole different story.
