Aftermarket stuff for Winchester SXP - anyone know where to find it?

[CobraGT]

Does anyone know where to find a +2 or even a +1 mag tube extension for a Winchester SXP? Also, I know ATI is making pistol grips (see link below) but I can't find anyone in Canada who carries them. Anyone seen these pistol grips in a shop, or at any Canadian online retailer??

Cabelas sells a stock with a pistol grip for it, never seen just the pistol grip. My friend bought the new model with the ghost rings and pistol grip but with the action release button behind the trigger guard it's hard to press.

Found the pistol grip at opticsplanet.com, and they ship to Canada
