for those that think it is important (i.e. the horse, not the rider) the ISSF list of firearms and ammunition used the shooters who won medals at 2011 World Cups > http://shooting.by/im/results/Industry_in_WCs_2012.pdf
It's always interesting to see who are the leading manufacturers. I'm wondering if the Steyr electronic trigger is responsible for it's popularity in air pistol at this level.
Very interesting to see Walther making substantial in-road in air pistol. I am guessing it must be the 400. Walther looked liked it had lost the plot with the 300. Steyr still holding its ground.
Misny I don't think the electronic trigger is responsible for those numbers as its pretty close to what they've had in the past. That said many are shooting the E version and had converted to from the standard version.
