Red KapMen's Quilted Vest

I am 192 cm and 120 kg. What size do yuo recomended?

What's the lengh for medium size?

Ok, according to the size chart, every man's chest is the same size as his waist lol How do you size this vest, or is it best guess?

Does this vest have an inside pocket large enough to carry a small caliber pistol or revolver? Thanks.
