My LCP is basically a 7 shot derringer with a glandular condition.
Like someone said, it’s better than nothing & likely to cause the bad guy to rethink his choices. A few officers carried a derringer as a b/u in uniform but my choice was a .25 auto laced into my boot.
He was lucky that it was the the toilet that was damaged and not the user...One day he went into the gent's room to do his "duty". Unbuckled his pants, derringer fell out, discharged, killed the toilet..
