The other issue, beyond bullet set back, is the rim gets chewed up, if you constantly extract and reload the same top round. There are reported instances of police officers that constantly load and unload their service pistols and when it came time to fire (on the range or in the field) the top round would not extract. Remedial action would not clear it...needed a rod to punch the case out. Inspect your ammo occasionally. If the rims are chewed up, replace the ammunition.One year sounds right. Afterall, your life is depending on it.
Also, if you carry with loaded chamber and unload often, rotate and inspect top round in magazine that goes into chamber when loading, if you don't you may end up with a bullet set back into case after many load/unload cycles thus risking extreme pressure on firing it that can potentially cause catastrophic gun failure.
Bottom line, unless by policy, don't unload and reload a carry gun all the time, not only for potential damage to the ammunition, but more handling/fiddling induces the risk of a negligent discharge. Leave the gun in the holster when you don and remove it from your belt.
