And they will ALWAYS get you from point A to point B. regardless of mileage, will run on whatever fuel you feed them, won't leave you stranded when you need them most, were designed within the past century... Etc.
All weapons fail, that's what they do. But some are more reliable than others. And then there are exceptions. I make hardcore Glock advocates upset when I tell them that the Glock I took my first class with malfunctioned quite a bit. It even did something that made one of the instructors say to all the other instructors, "Hey, you guys have gotta come here and check this out. I've never seen this kind of malfunction before."
Just my humble opinion: don't worry about scratching up your nice metal guns. These are tools, not fine art, and you can't take them with you when you're gone.
