N/A History of Recoiless Air Pistols

I have a Beeman Original 6, one or the rebranded Diana models, two each FWB 65 and 80, a pair of IZH 46m, several of the Daisy 747 and 777 models and a HW 75. Everything mentioned after the FWB's is a SSP and therefore recoiless. Of the spring air types I like the FWB's best, not as bulky and heavy and just shoot better.
