Benman,
We can own semi-auto handguns in .22, .32 acp and. 380. Personally I have never been able to warm up to the .380, especially in a gun designed to be a 9mm or .45. Can you imagine that waste of space, a .45 rechambered to .380, odd but true.
I settled on .38 special because they sell 125 grain +P+ and 158 grain +P for it. I figure that if six in the gun and four speedloaders don't solve the problem an auto wouldn't have either. Mac
