Always found that air pistols copying rimfire or centre fire firearms are a bit of a compromise. I think the Schimel was the first CO2 copy emulating the P08 (Luger). Better performance is found in dedicated purpose designs, but I think that some UK shooters are frustrated not having handguns and want copies. I had 120 pistols and revolvers overseas but don't really miss them here in UK with the restrictive rules we had when they were around. I now prefer using proper target air and C02 pistols for accuracy and power output.
