The nicest for pure plinking pleasure are the tin grip and early post war Juniors.Lovely build quality and accurate in a compact and easy to cock package.
The Junior's are my favourite over lever Webley pistols the MK2 can be ignored,though.
The larger slant grip post war Senior with a good trigger is probably my second favourite followed by the blued steel Premier's.The MK2 Premier can also be ignored.
I had a Tempest,they are a very functional pistol with a great trigger,but total carp build quality,monkey metal casting, plastic and roll pins!
