Havent been to West Malling for a year or so, but it was a good air rifle shop, the out of town bit had a range and good selection of airguns. Potters tends to have a resonable range of new and 2nd hand stuff, and Chris is a nice bloke. Theres also a 2nd gunshop in Tunbridge Wells, all they sell is shotguns and rifles over 100 years old. Really interesting place to visit and the owner is happy to chat. Tunbridge Wells is also a nice town to visit if you are bringing familly.
