I'm looking for another hand cannon and was thinking about one of these. I have a 50 AE Desert Eagle, 454 Casull Raging Bull, LAR Grizzly 45 Win Mag, and Super Blackhawk in 44 Magnum. I believe Magnum Research makes one in this caliber, but it lists for well over $1200 and one Desert Eagle is enough. I saw that Galena Industries (makers of the Automag pistols) advertises one on their website. Does any other company make one? And, how does the 440 Corbon compare to the above calibers? Thanks.
