Unfortunately there are no "good" walking feet available for the 301. There are many that are marketed as fitting the 301 and they do, but they are too wide for the feed dogs. There is not one walking foot one the market that will do what it's supposed to and that is feed the top in conjunction with the bottom feed dogs. I'm hoping that eventually some one will get smart and engineer a proper walking foot for the 301, as of now you can either got without or buy one of the modified ones for sale that will fit, but won't work 100% like it should.
Your 301 will take different feet from your FW.
