Recently Dragman attempted a 1911 conversion to .460 Rowland and unfortunately it did not work out as planned (Sorry about that Dragman ) at the time I was unfamiliar with the cartridge so I did some research online and there were a few sites, but not much on it.
Well today for no particular reason I decided to look it up again. And it appears that Johnny Rowland is making another big push for the cartridge. He is working with Master Piece Arms and they are making a pistol and carbine. And he has conversion kits for both the S&W M&P .45 and the SA XD-45.
XD-45!!! 13+1 rounds of .460 Rowland.... Whoa.
I am not trying to argue the merits of this round for self defense but I wanted to post the site for anyone else who might be interested.

Edit.... Looking around it appears the XD conversion has been available for about a year from someone else... oh well new to me..
