Heres what I use. My girlfriend bought it for me a few weeks back. They have it for the 500 and 835. Just a heads up for when you purchase your gun. If I could do it over again I would go with the 835 so I could shoot 3 1/2 for turkey. I have been shooting Lightfield hybreds and they are awesome. I stick to the 2 3/4 and they still kick like a mule. Good luck to you.
