Thanks Andy. I think I met you briefly on the JJ stand at the game fair this year.
I'm actually down Penshurst way next weekend for my wife's sisters birthday so I'll see if I can sneak off to have a look. I also wanted to go to Chris Potter to have a look at the MXS.
Genuine question as I'm sure you know your P-guns - what makes a used MX12 a potentially better buy than a new MXS ? I know they are both coil-spring triggers, but not much beyond that if I'm honest.
Anyway, will PM you once I figure out what the arrangements for next weekend are.
