Re: Technical question re: old load handgun kept in storage
Depends on the conditions the gun was stored in.
One of four things will happen.
The gun got wet and rusted tight, and the dang thing won't do anything. Trigger won't pull, cylinder won't turn, slide won't move, magazine won't come out, safety won't move. It be broke. Sucks - but no danger.
The ammo, because of oil contamination or extremes of heat and/or cold will not work, and it will go "click". Again, no danger.
The ammo was semi-degraded because of (see above) and it gives a kinda weak "pop". This is the dangerous one. The bullet might have gone into the barrel, but not made it all the way out of the barrel. If you, without checking for a plugged barrel, and removing the plug if there is one, and try again, and round two goes BANG, and round one HAD plugged the barrel, you can have what is referred to as a "KABOOM". That's when the gun explodes in your hand. NOT FUN.
The fourth possibility is both the gun and the ammo work fine, and it goes BANG BANG BANG BANG like it's supposed to.
