Just picked one up for 370$. Lightly used. The owner said he only put 40 rounds through it and it looks like it too.  Anyway, I don't know much about them but I know that I've always wanted one in .45LC and that's what I got.  Anyway, about the ammo; these can handle stout defense /big mean critter loads correct; or should I stick to the light stuff?  I plan on reloading so cost isn't too much of a concern at this point in time.  Oh, did I do ok on the price?  

You got a good deal on one of the strongest sixguns ever built. It'll take just about any 45LC load you can safely fit in the cylinder.
