I went out and bought one yesterday and had a go at setting it up today.

I can't see the link about trigger fettling?, can someone repost it please?

I did set the trigger to it's lightest adjustment which improved things, and I turned the power down to around 4 as I seem to be having trouble zeroing it with the red dot sight I got with it. It's probably me though, I know how to zero things, but the groups are just way to big, but as I'm not used to pistols it's frustrating seeing other peoples groups and them saying how accurate it is.

I tried resting it on my arm and got better results, but resting either the cylinder or fore grip on the back of a soft chair was rubbish, it looked like it was not moving, but the groups would suggest it was kicking up, but you could not see it?

Does anyone have any tips for an effective rest for zeroing, I get it that I will never be able to do it accurately freehand.

Thanks
