I am now just wondering how I can get the twang out of it. Something is not quite right with the design of this gun I think.

It's OK at 9.5. Re the twang, a decent spring guide should sort it out but be prepared for a power loss. The cylinder is not very large hence he low power which can't easily/realistically be improved upon.
My very first airgun, and the (successful) shots I took with it meant that I never complained about the power, and mine was probably pushing out a lot less than 9.5.
The 3 ball trigger? No biggie. Just grease the balls in place while assembling.
