Steyr LP50, fairly low powered as standard but can be uprated by the importer I believe to be pretty much on the limit, superb accuracy and great fun, mine was fitted with a hakko red dot on top of a hydrographics custom weaver rail

I have recently bought a Crossman 600 pistol though, 12 shot semi auto and mines doing around the 5ft lb mark and accurate as well!

Goes through the CO2 capsule on three full mags and it's addictive so might cost a bit to run..... Hey Ho
