Okay, to keep things on as light a note as possible, you have a point. One cannot say their Parabellum is battle-worthy because it has been carefully cleaned and maintained. We all know the P-08, while a fascinating work of machinery, was not suitable for the down and dirty mud of the trenches. However, the 1911 was. In WWII, the BHP proved likewise, as did the P-38. The CZ-75 has proven successful in the poor conditions of southern Africa and Central America.
However, I tell you that I refuse to abuse my handguns. My CZ's, my Witness, Webley and Nagants, Colt Trooper and a few others get treated well. They have always performed for me and they are of designs that have proven their worth. I am unwilling to mistreat something in which I have invested so much money and would not take pride in such abuse. I would not brag that I did not keep it clean, that I threw it in the mud and then fired it, or that I left it in the rain. I treat my sockets and wrenches the same as my pistols, wiping them off after each use. My rifles ditto, even my work Jeep, which goes through all the grief that Hummer owners would cringe at, gets thorough maintenance, even if the body is banged up from stumps and scratched up from limbs. I keep it clean. My knives I use to cut with, but I won't cut wire with them nor use them as a hammer. I have wire cutters and hammers for those jobs.
Now, if you abuse your Glock, which I must assume you do, then fine by me. You can even shout to the world that yours is better than mine because yours has been abused and still fires whereas mine has not been abused (but still fires). You can boast that because you mistreat your firearms and they still work, then they must be better than the other guy's goods because he keeps his clean. You will be wrong, and the only point you will be making is that your stuff is ridden hard and put away wet.
