Leshiy leakage UPDATE

That is only a 3 bar drop, 1.3% of 224. This can occur as the air you've just filled cools down and contracts. Also moving the gun from a warm location to a cool location will cause the pressure to drop and vice-versa. I have noticed this with my new Edgun Matador R5M immediately after hand pumping.

Thanks 

it is not immdiately... but from last Fri, sigh!
