I just bought the same gun a few weeks ago. Does yours have Wood or synthetic stocks? I bought the wood stocked one.
Here's a link the the thread about
Mine.
I really like the Fiocchi Low Recoil buckshot for a HD round. 9 pellets of 00 buckshot at 1150 fps and it recoils like birdshot.
As for accessories, I like to keep my guns simple. Only thing I've got on mine at the moment is an Ace slip on shell holder. The cheap sleeve that holds 6 shells on the buttstock.
I'm also gonna get a mount for a flashlight, since it will serve HD duty, but have no other plans for her. Other than ammo and possibly other barrels.
anyone have an opinion on the adjustable M4 style stocks? I was thinking I could leave it in the shortest position for my wife and easily slide it out to my size.
I'm not a fan of the M4 style stocks on shotguns. That's my opinion, so you may find they work well for you, but one thing you need to be aware of is the safety location on the 500 makes it hard to use with a pistol grip style stock.
I don't use the safety much on my gun, most of the time it sits with loaded tube, empty chamber and hammer down. That way I can just grab it, pump and it's ready to go. Now when I'm out on the range, the safety gets used.
Hope to get mine out to bust some clay targets before it get too cold here.
