If you're lucky you can find a 14" barrel in 357mag. They used to have them in 44mag, but now they are extremely rare. My 44mag that I had felt like there was no recoil due to the weight and two recoil rods that have two springs on each one.
One of the best shots of my life was with my old desert eagle 44. My brother in law and I had stuck a 4x4 piece of wood through the ice in a pond as a target and when we got back on shore he bet me five bucks I couldn't hit it. Well, I fired one shot and splinters flew everywhere. I didn't collect the $5 because I didn't think I could repeat the shot, bragging rights were worth more than $5.
Desert eagle are awesome but they come at a price. Not only barrel, magazine, but also the bolt have to be changed when switching calibers. You have an awesome gun!
