Sometimes we find ourselves making dumb arguments... seemingly for the select purpose of arguing.
Semiautomatic firearms are OBVIOUSLY designed to strip rounds from the top of a magazine. Beyond that (FACT) the rest is just pointless arguments.
Understand that while you most definitely can, successfully use the butt of a handgun to pound a nail flush, and depending on the size/head of the nail, the receiving surface and the particular handgun -- it may actually be possible to do this with ZERO ill effects...
...it will still be a dumb argument and shouldn't be encouraged.
Likewise, if the enemy is bearing down on you and you have one round and no magazine, slam away and it will likely work, if you are shipwrecked and your handgun is the ONLY thing that will plug the hole in your sinking raft, go for it but seriously, give up the dumb argument that it's a good idea.
