I spent a few summers while I was in college working in construction. I'll be frank with you: The work was hard, often difficult and dangerous, (Especially when we were high in the air.) and my body was in almost constant motion. Know what? I'm 100% positive that I wouldn't have carried any semi-auto in C-1 while I was working in the trades.
What for? I always had a 22 - 28 oz. framing hammer on my belt; and using it precisely with a great deal of force was second nature. All of the experienced crew members could sink an 8 penny nail with a tap, one very hard shot, and a bounce. (Sometimes we did this, virtually, all day long! The work was hard; but the pay was great; and it went a long way toward getting me through school.) Then, there were always the crow and pry bars; each a deadly weapon in its own right.
Once in awhile we worked in a rough neighborhood; but, quite honestly, I never felt the need to actually carry a gun. (There's a lot of extra risk there, too; and, in construction, your body's your ultimate tool and the only real way you have to earn a living.) The fewer risks you take the better; which is, 'Why', even though I could, I never ran ridge boards. (Doesn't pay anything extra!) All this said I'll point out that the best moisture protectant I've, yet, found for any firearm is
FrogLube. Applied correctly and raised to a high polish with a microfiber cloth it will prevent rust on your EDC for, in my own situation, as long as 3 or 4 months without needing to be touched up.
(If I've been preaching I apologize!) :wink:
