This clandestine pistol is modified to:
-be electrically fired
-be extremely quiet
-shoot a deadly poison that emulates a heart attack and doesn’t show up on autopsies
-be capable of shooting a target without them realizing they’ve been shot
-work at 100 yards

But these aren’t being fired using gunpowder, so the thermal curve would change dramatically.
Strongly agree with all your other points though.
I could see it as a small BB gun, with a range of 10 meters instead of the advertised 100.
