I looked long and hard for a 2 3/4" Six here in CA. Of course I found a blue 'Security Six" .357 in great condition for a fair, if high, price just when I'd spent my entire allowance on other guns!
Three years later I found a near-new 2 3/4" blue "Police Security Six" .38 at a really decent price locally and acquired it (with the aid of a little domestic perjury....). It's not goin' anywhere except to the range!
I agree that these guns, once acquired, stay with that owner for a long time. Your hands and eyes love them, so you do too. Finding them here in CA is complicated by the fact that few or none of them are C&R vintage yet, so they can't be "imported" to a CA dealer legally.
SO, if you are thinking of moving to CA (do I hear snorts and upchuckles?) BRING ALL YOUR SIXES WITH YOU! We want them! (And with the price of everything else out here, you may need the cash....).
