Notice the rounds below the pistol. 2 are shorter than the other.
Know how that happened? These are all Speer Gold Dot .45 ACP cartridges. The center one is brand new. The others
Used to be, I came home from whatever my daily activities were and at the end of the day, I'd pop the magazine out and then eject the round in the chamber. I'd then lock the slide back and leave the firearm on the table. This was primarily so that the firearm had a chance to dry out after being carried IWB.
In the morning, I'd replace the mag, drop the slide, set the safety, then drop the mag and replace the round that I had ejected the night before at the top of the magazine.
Do this more or less daily for a few weeks or months, and the result is the two shorter rounds you see below. The bullets are set back significantly, and the chamber pressures will, if the rounds are fired, be significantly higher. Dangerous? I dunno. Not Good? You betcha. I'll knock these apart for components and reload them for range rounds, but I won't shoot them as shown....
I used to change my carry rounds every 3 months, now I do it monthly. I burn up the personal defense rounds in my CCW magazine at a range session just to be sure that fresh ones (even though expensive compared to reloads!) are at the ready, not rounds exposed to sweat, vibration, changing temps, and the above mentioned bullet setback. And I tend not to clear the firearms daily unless it is REALLY damp, or really dusty, etc. Likely the CCW piece will be only unloaded and the action opened for the weekly cleaning and oiling....
At our house, we have no children, and adults are either trusted ( Brigid, Og, etc) or firearms are put away or carried on our person: either way, out of reach, or adults are closely watched (we aren't terribly trusting of folks we don't know well. We treat people we don't know just like children when it comes to firearms.) As Tam has pointed out many times, handling yer heater adds to the likelihood that you will have a negligent discharge.
When was the last time you inspected the rounds in the firearm you carry at the ready to save your life or the life of someone dear to you?
