Lee,

There's good news and bad news. The good news is that shooting jackets for wheelchair users exist, the bad news is that there are no "off the peg" solutions. You have two options, either get one made-to-measure (expensive) or have an existing jacket altered. The rules regarding wheelchair jackets are on page 26 of the IPC Shooting Rules and should you decide to go down the alteration route these are the criteria your jacket should meet.

Vic's advice to get in touch with Pippa Taylor at Tenpointnine.com is spot on as she can fully advise you about both options.
