Ernie Pyle wrote an article about an ordnance company after D-Day. They gathered weapons from the battlefield and aid stations., stripped them down. Set up buckets of solvent (gasoline if I remember correctly), bolts in this bucket, gas cylinders there, etc. Slosh, scrub, reassemble, lube, test...

Next time you're at AGC, walk across the drive to the patterning range. Seriously, would we complain about not hitting at 100 yards with a rifle we hadn't zeroed? Nevermind, this is MDS.
I have a Shok-Buff in my Govt Model. It goes on the guide rod and keeps the dust cover of the slide from smacking the guide rod. Mine gets kinda smashed and ugly after about 1000 rounds. I don't think John Browning anticipated the number of rounds we put through our pistols.
Sometimes my Informed Delivery items arrive that day, sometimes four days later. I think some days my letter carrier gets half way through the route and says eff it.
