I've got an SMK Synergy XS26 Air Pistol. It's a pretty satisfying gun to shoot, but ever since I got it, it's been intermittently dieseling (when lubricant gets from the cylinder into the barrel and ignites under pressure). It dieseled whilst attached to my chronograph and was measured throwing a 15.89 grain pellet out at 430 foot/s. That works out to around 6.53 ft/lbs, which is over the UK legal limit for an air pistol! A louder bang and bit of smoke might be a bit of fun, but getting prose...
