I dont shoot 10 meter air pistol as often as I used to as the arthritis in my hands can make it a painful experience and it also gives me some problems when trying to judge the grip strength as some of the sensitive feed-back feeling is lost, but I did pick up a Steyr LP2 the other day just after I put my rifle down and shot an almost perfect card with it (49 ex 50) - but I was still wearing my rifle shooing jacket !

Maybe having arthritis in the pistol hand and wearing a heavy rifle shooting jacket is an especially good combination?

The rifle jacket is probably illegal in air pistol competitions .....but as far as I know the arthritis is still a legal option
