My wife is nervous about my leaving a round chambered when the gun is not on my hip. So every night I unload my pistol and remove the round from the chamber, put it back on the magazine and put the mag back in the gun. Every morning when I get dressed i rack the slide and holster my weapon again. I was wondering if constantly chambering and unchambering the same round every day might affect the reliability of the round. I would hate it if one day I needed that bullet and the gun went click instead of BANG.
Any thoughts?

Rechambering the same round can cause setback of the bullet which can cause high chamber pressure and a catastrophic failure. This can cause a BANG to become a BOOM. I suggest buying a small gun vault to store your handgun at night.

A person is at risk of bullet setback, which can happen when the same cartridge is loaded in a semiauto pistol multiple times. Basically the act of the slide slamming the cartridge into the chamber also jams the bullet nose into the feed ramp. Over time, there is risk of pushing the bullet deeper into the case, which can raise pressures and result in a KABOOM.

Here is an example of bullet setback:

You are the exception to the rule. The new Hornady Critical Duty rounds were explicitly designed with cannelured bullets in semi-auto rounds to prevent bullet setback.

It is still better practice to leave your gun loaded all the time. Repeated loading and unloading on a daily basis is unnecessary gun handling and is by definition more dangerous that simply leaving it loaded.

I rotate my rounds when unloading/reloading for range time. For example, if the round in the chamber is round 0, and then the rounds in the magazine are numbered (top to bottom) 1 to 15, when I reload the gun, the former round 0 gets moved to magazine position 15, and all the other rounds move up 1 place in line. Thus in fifteen unloading/reloading cycles, each round got loaded once instead of the same round getting loaded 15 times.

if you don't have kids I don't see the problem. Is she worried that you or her is going to go pull the trigger on it?
