I consider fanny-pack carry to be equivalent to off-body carry, something of which I personally disapprove. Here's why:
• Most fanny packs can be snatched pretty easily, even when buckled around your waist.
• If you ever take the thing off, it is easy to momentarily forget it, and thereby to lose control over the pistol within it. ("Ooh, look at what I found, Mommy!")
• Presentation from even the best-designed fanny pack is pretty slow, and never quiet.
• Furthermore, just about everybody, especially every cop and crook, knows what's inside a fanny pack.
I've tried almost all of them, and none of them work well enough to make them worth the risks enumerated above.
There is, however, one "non-fanny" pack I've tried that is more snatch-proof and less "forgettable" than most. But it attaches directly to your pants belt, so it can't easily be removed (which, as I've noted, I think is a good thing).
Presentations from it are just as slow as from any other fanny pack, and cops and crooks already know all about it, but it's worth your investigation.

Note that if you use any kind of pack, you will need to practice extensively with it. None of them are "easy access." All of them require zipper or flap manipulation, and none carry your pistol in an ideal position for a quick grab.
