I read the linked czforum explanation of dropping the hammer on a live chamber, and something doesn't ring true. The article claims protection via the half-cock notch and the inertial firing pin.
If you pull the trigger back to a certain point, the hammer will drop past both notches. Reliance on the half-cock therefore requires the user (who just fucked up by letting the hammer go and most likely won't be feeling overly wonderful about that fact), to release the trigger before the hammer can rotate past the half-cock notch.
Reliance on the inertial firing pin requires faith that the hammer was retarded enough in the fumble that it won't have enough oomph. God help he with touchy primers.
The article further claims protection via the firing pin block on the B model. I'd imagine that pulling the trigger such as to release the hammer would disengage that safety, and we get into the same problem as with the half-cock notch.
All this really is unimportant if you follow through on #1 and keep it pointed somewhere safe. Me, I don't have a berm at home. Neighbors would complain of the noise. Fiancee vetoed the snail catcher. Oh yea, and that whole trigger discipline thing.
SA was good enough for your grandpappy, it's good enough for you. Fucking whippersnappers, I tell ya
