I think you'll find that CO2 pistols are the most commonly used with the Smith & Wesson 6" barrel the most common. Many of the semi-automatics are also represented, Colts, Beretta look-alikes etc. and several of these are seen, often with red-dot sights as there is a separate class for this. We also have quite a few shooters of Brococks (so-called self-contained gas cartridge) pistols as well.
