Hi, I am about to purchase a new firearm, a FN Five-Seven, and I would just like to make sure that I don't make a purchase that might not be legal. I have read as many gun laws of Washington as I could possibly find and the size of a magazine, be it pistol or rifle, was never addressed. This gun comes standard with 3 magazines which can either be 10 round or 20 round. I would like to have the 20 round magazines just because while at the range the lack of reload time would be nice, but if it isn't legal to have them, I am happy to order the 10 round magazines.

Also, I know that this isn't pertaining to hand guns, but is there a limit on rifle magazine sizes? I see many rifles being sold that come with 10, 20 and 30 round magazines and, again, I would not like to own anything that would be illegal and make firearm owners look bad.


Thank you for any help anyone can provide.

Kenny.
