    As in any of my weapons I think of "worst case" scenarios and want them to function in any environment. Even though I don't live near a desert or a jungle I want them to operate as designed in those environs. Likewise, as far as hard use, even to a "go to war" degree, I want it to work. So if, God forbid, I ever had to put down enough rounds to smoke the barrel I'd like to consider how best to address that scenario.

    The exhaust wrap sounds interesting, as I'd only need maybe 4 or 5 inches of it wrapped around the end of the tube where I grip with the thumb-over style.

    +1 for gloves. I too am "just" a civilian, but once you try shooting from barricades or trying to see how fast you can go from standing to prone and hitting a target, a glove will greatly improve the level of joy you get out of your range time. I compete in IPSC Rifle and even though we rarely shoot any extended strings of fire the firearms do tend to get warm-to-hot, and there's often the need for supported shooting positions from barricades made out of old pallets and/or unfinished planks that will give you splinters just from looking at them, or to be able to go prone as fast as physically possible.

    That's actually false.
    Water has a very high specific heat capacity. Wetting your hands before touching something hot prevents burns. It's why you can lick your fingers & pinch out a candle without getting burned. Ever see the experiment where a guy wets his finger & then stirs molten lead?

    Not saying you won't get burned, just that the added water will delay the burn, not quicken it.

    I was thinking it's closer to 4.186 J/g but I'll take your word for it.

    I wear gloves for the military and work when using a carbine but never have preferred them. FWIW I've ran numerous carbine classes without gloves and never had an issue. Even when I wear gloves I cut the finger tips off and on occasion used a tube rail for said classes.

    All I know is, after I won the 499 class shoot off at Gunsite and received my certificate, the instructors also presented me with a second, framed certificate- which was covered in fake blood and bandaids- to commemorate all the cuts and gouges I had sustained during the week.

    That's why I learned to work with gloves whenever doing anything requiring aggressive manipulation, etc.

    Actually very true. A wet glove in contact with anything well above 250 deg. will give you a nasty steam burn. Time spent around arc welded parts will teach you this lesson quickly. You will figure out just how fast you can get that glove off of your hand.

    OK, fellows, let's drag this mule back to the path shall we?

    Can we agree "gloves good, burns bad" and move on?
