My CZ Slavia 634. Amazing little thing. 25mm piston with synthetic ring at the rear from the factory. Manual barrel latch. Superb barrel. Very, very accurate. Twangy as standard but shoots sublimely with its TbT top hat and guide. Very civilised.

Gamo Vipermax. The super-lightweight rodless 25mm piston giving very little inertia. Again, once de-twanged with Welsh Willy guide and top hat, very refined.

My cosmetically challenged early Supersport. Very accurate. Again, extremely civilised with its TbT guide & top hat.
