Manufacturing tolerances in both of these items can add up to that or more. Knowing manufacturing tolerances differ and firearms/ammunition from foreign nations may not comply with SAAMI specification, the firearms are built to withstand all those minor differences

SAAMI pressure for both cartridges is 24,000 PSI
The J frame is built to take .38 Special pressures so .22 Mag should be no sweat.
