If you can handle the recoil, yes the 44 mag is a great caliber. But factory loads can get expensive. S&W makes a lightweight line in 44 mag.I see that you can get lever action rifles in .357 mag, .45 colt, and .44 mag. I intend to carry the pistol in open carry anytime I am out of the yard and keeping it handy when I am working. Would you recommend the .44 mag?
Before you make any decisions though, I would try a revolver in every caliber to see which you would prefer/can handle the easiest and best.
