You have discovered that M10's are bricks!
The original M10 was prototyped in the US and was the same external dimensions as the M13. The concept went to Germany and Lugerheads completely re-engineered it into the boat anchor it is today.
Sorry, the extra weight undid everything that makes a P7 a P7.
