What about the fact that, according to some of what I have read (and it is totally logical), your firearm is more likely to malfunction when it has been disassembled and then put back together since the last time you fired it?
Isn't there something to be said for having verified proper function since the last dis-assembly?
For those that do not know how to maintain, reliably reassemble and check their weapon, that is true. Where I learned to take care of my weapons, we were required to be able to take them down and put them back together and able to function properly, blind folded. Test fire was not an option. Sort of a ZEN thing.
We cleaned our weapons a MINIMUM of twice a day in the bush, more if you were involved in any fights. Test fire was not part of the drill.
After a fire fight, orders were to take care of the wounded/dead if any and count heads, defensive positions when necessary, 50% of the rest of the troops were to reload their magazines and quick clean their weapons, then switch, and distribute any extra ammo. The NCO's & SNCO's checked their fireteam/squad's personal and heavy weapons if any and radio's. Then count weapons, ammo, radio battery's, etc...... Firing your weapons to see if they worked wasn't anymore an option then, than where I live in suburbia today.
Where I learned to fight, and did my post training graduate work, turning your light on in the middle of a firefight to fix your weapon, even under a poncho, was not conducive to a pain free existence.
Nothing wrong with test firing a weapon, but not very practical for most folks. Particularly those who carry a weapon for a living. Learn how to maintain your weapons properly is my best advice for any professional.
Good luck.
