I'll chime in here. First off, Daath: We do not
have gun registration, per se, in this state. Yes there's a federal paper trail when you buy any gun from a dealer and a state trail if you buy a pistol, but that's a far cry from the true gun registration of Kalifornia, et al. If you sell or buy a pistol privately the trail stops there and there's no requirement to "re-register" it, or to maintain any kind of registration after the initial purchase.
Crunch14: Welcome to the forum! I think you'll find that most people here who OC also have a CPL (Concealed Pistol License, as it's called in WA state.), even if we chafe at the idea of asking permission from the state to exercise a right, first of all for convenience (so we don't have to unload in a vehicle), and also to be legally covered if our sidearm just happens to end up concealed.
Someone WILL chime in here if I'm wrong (no error, however small, goes unnoticed around here for long:quirky), but the few here who do adamantly refuse to get a CPL simply pop the mag when they get in the vehicle. There is no requirement, under state law, to "secure" the magazine or ammo anywhere specifically, it just can't be in the gun while you're in a vehicle. This also applied if you're riding
in a vehicle (bus, etc), not just driving.
My two cents on the matter is, much as it sucks go ahead and get the CPL, if only so you don't have to unload in a vehicle. I OC 90% of the time (I hate having
to conceal), but I like having the option of concealing if I so choose. It can get tricky to stay warm & dry in the winter & not have your gun covered. Also, remember if you're loading unloading in a vehicle, especially if you have to chamber/unchamber a round, you could be asking for an ND. It's generally agreed that any handling of your sidearm out of its holster other than at your home or at the range is asking for trouble.
Ok think I covered the basics here, one of the local forum gurus will be along shortly to correct me
. Also, we're having an OC meet in Bellevue this Saturday, as a matter of fact. Dixie's BBQ I think, dig around for the thread and you'll find it. Also grab the WA gun rights pamphlet from the sticky thread, all the relevant laws are referenced in there and it might answer some more of your questions.
