I am a huge fan of the 22 mag. I have a custom Taurus model 941 with a 3" barrel that I carry every now and then. The 22 mag is very underrated, thus I am taking advantage of this and buying ammo while its cheap! When you look at the energy produced from the 22 mag round against the 38 special, 32 acp, 25 acp, and the 380 you find that the 22 mag (out of a pistol range barrel) is able to compete with than them all. Here is the info to back my claim.

22 MAG
Winchester Dynapoint mag RF. It is a 45 grain bullet in a full length mag case but its velocity runs around 1550 fps... and 250 pounds of muzzle energy.
Barrel 6.6"
