Re: From semi-auto to auto
There are/were select fire pistols - variations of "normal" models like Beretta 93R or so designed from the start, like the broomstick Mauser, Stechkin etc. The reason they are not widely used is that they are impossible to control without additional implements, like stocks and front handles, otherwise all rounds after the first one go up into the ceiling. And if you have to attach all sorts of external things to your handgun - better just get an SMG.
