Sometimes that's the way, not just with shooting but as time goes on you revisit something that had the seed planted back yonder.
Never tried a Tempest, but have shot many older Webley pistols, that 1" at 30ft seems a familiar advertising claim. Easier to say than achieve, the early pistols have a short/ shortish sightbase which hinders things, but that tiny front sight isn't or wouldnt be my first choice. Thought about "accurizing" one for fun, complete with a decent set of sights. Not trying to build a target pistol as such but just to see what I can make of it but never got around to it.
