BIANCHIB12 Tan Reversible Sport Stitched-Belt

I see where we are told to order a larger size due to the belts running small. These belts are priced more for larger sizes, see where I'm going ?

is the buckle removable?

Will this belt hold up to supporting a Colt Pyhon .357 w/ double speed loader case ?

I view two versions, brass and/or silver buckles, are both made in Mexico, even though description states USA as origin?
