Hi Duncan,
When we used to shoot the 10 meter MPL as a club event we used to give the "kickers" a 2 point per card bonus as that was thought to be a reasonable compensation factor to make a realistic comparison between what might have been scored with the same shooter if they had used a recoil-less MPL pistol at that distance.
Obviously we had to take a"stab in the dark" when we came up with any figure to use and this had to be modified as we gained "real life" experience after the first series had been completed.
The GAMO Centre became the favorite pistol to shoot in the 10 meter MPL for some time as it was good value when shot against a recoil-less pistol as it was often capable of scoring just as good - even though it was a kicker... and then you had the extra points bonus to add on top as well!!
The loose grip and letting the pistol "do its own thing" after the trigger is released took a bit of getting used to but once we realised that the pellet had already left the barrel before it jumped up in the air we began to understand it a little better.
When I penned the rules for the 6 yard MPL postal series it was decided not to give any kicker bonus as firstly we had some experience of just how good kickers can be shot and secondly the shorter distance also helps to reduce the difference more than what we experienced at 10 meters.
The Original Model 5 was another favorite and some got on well with the HW45 and Webley springers too ( ask IJ ), but the GAMO Centre was by far the most widely used MPL pistol because it was cheap to buy and with practice it became a formidable points scorer.
Not everyone got on with the GAMO Centre ( ask IJ again ) but many of us got on very well with it and after a strip and clean-up and some decent lube it was even better.
Stay with it - remember to hold it loose enough to let it kick and with practice you will come to terms with it and probably surprise yourself at what you can achieve with it.
