Of course they do.
not to powerful
That's off the top of my head, I didn't even cover most of the things like concealability, weight of loaded gun, ease of loading, trigger pull, availability of ammo etc. etc. etc.....
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
