Birddog, from what I've read of the law so far it doesn't appear to have any effect on revolvers, it is very specifically aimed at detachable magazines. I am no lawyer though so you may want to consult someone better versed in legalese.
Thanks for the input. I've read the legislation twice now. It is VERY fuzzy. It doesn't just specify detachable magazine. I don't have it in front of me now, but it basically says "magazine, drum, other feeding device..etc". I haven't gotten one response from anyone who KNOWS, including the State Police, if revolvers are affected. Their own list, on the State Police website admits that the list is incomplete.
The law seems to focus on 'assault weapons', but doesn't specifity if the magazine rules apply to pistols and there's nothing at ALL anywhere mentioning revolvers, whether they're included or excluded from the capacity regulations.
In the meantime, I'm erring on the side of caution and not buying a 9-shot revolver.
