I lent my "new to me" Pardini P10 to a fellow club member last night and he was shooting very well with it until he reported that all of his shots had suddenly started going low on the target.

I went over and checked his target and all of the shots were well below the black - even though they had been correctly placed on his previous cards shot with the same pistol, so I took a shot to see if I could see what was going on and scored a perfect 10 and then two nines with all three shots being very tightly grouped.

John G then took two shots ( again on the same card) and both of his were nines. On handing the pistol back to the club member he shot low again, lost his confidence and gave me the pistol back so I put up a fresh card and started to shoot it.

Some shots were good but then the pistol locked-up and would not shoot. Once the pellet was cleared I tried again and sometimes the pistol would shoot and sometimes it would not.

Guessing at it I think it may be a sticky valve that may have contributed to those low shots and is why it will shoot sometimes but not others - but does anybody have any experience with Pardini SSP pistols and has had any similar problems?
