I use the 7 mil blue nitrile gloves which I buy by the box at Harbor Freight
These blue gloves typically last two gun cleanings before the finger tips wear out.
I sometimes wear the 9 mil black nitrile gloves for gun cleaning, but not as often as the blue, because it is harder to pick up small screws, etc.
I regularly use the black nitrile when working on my vehicles. I wear them under my Maxiflex gloves
These maxi flex gloves are a more durable wrench pulling glove, but they leak. After a day of replacing ball joints, tie rods, control arms, my arms are covered with grease up to the elbow, but once I strip off the maxi flex and nitrile gloves, my hands are clean. Sweaty, but clean. I want as little skin contact with industrial chemicals, and that includes, greases, oils, and gun cleaning chemicals. Your skin is porous, if you have not figured that out, just rub baby oil on dry skin. Keep industrial chemicals and solvents off your skin, out of your blood stream. Your knuckle dragging monkey ancestors did not evolve with the oils, and oil additives, or the solvents, found in gun cleaning products. You have no idea just what that stuff does to your endocrine system

62,000 chemicals on the market at the time were listed on the original TSCA Inventory of Chemical Substances.[22] TSCA "grandfathered" these 62,000 chemicals, allowing these substances to remain on the market without first assessing toxic impacts.
