Higher power rounds - .38 special, .41 and .44 mag, etc
Dad and I were out shooting today and I found some of his old .38 special rounds. He had a revolver that used them, gone now. It got me curious about some of the higher power rounds. A little over a month ago I took a CCW class and asked one of my instructors about rounds that would be good for bears. He suggested a .44 magnum.
My question now is regarding different calibers of "higher power" rounds (not the standard .380, 9mm, .40, .45 pistol rounds). What other more powerful rounds are there, and furthermore - are there any semi-auto/striker-fire pistols that shoot them?
Looking around it seems the only guns that shoot the magnum rounds are revolvers.
