There's a horror story out there about every product that has been around long enough but on average Toyota and Miroku make excellent products.
Miroku makes better than decent shotguns. Most of Brownings other guns I happen to like a great deal, especially the BPS shotguns and the Buckmark pistols. It is not a brand issue with me, nor a Made in Japan issue... it is a ridiculously poorly designed action with a ton of shortcuts. Love the "bedding" with hotmelt glue!
