I've no info that the tests were a hoax, nor can I find any. Many organizations and agencies consider the tests' data credible at this time. Alpine goats are not endangered. They are domestic like sheep.
You are right. A .45 ACP ain't no pocket gun, even though some are pretty small. Yes having your hand on a pocket pistol is indeed a great tactical advantage in lots of circumstances. An M4 in the hands is too for that matter. There's 140 ways to cook a chicken, we all have our own technique...so long as the doctrine is the same.
You are right, 9mm comes in very good pocket guns. I think I'd just get a .40 though, cause they come in exactly the same platforms as 9's with most makes, minus a couple shots.
The smallest pocket gun I been hearing good things about is from Kel-tec. Supposedly smaller than any 9mm by a noticeable amount, holds 7 or 8 .380's. Some cops been carrying them as back-up for several years; after a couple thousand rounds they still like 'em.
Never say die!
