I've got a 21" one that I can't legally carry (felony). It's easy to work, but retracting the thing is easier if you have a mallet (so you don't scratch the finish near the seals) to hit the side of the section joints to loosen them. I've heard of people breaking them (practical tactical forum), but I've never hit anyone with mine. The 21" is pretty short extended, the 26" is a better length, but is about an inch longer closed. If you can legally carry it in your car, go for it. I have a Maglite for that sort of thing, if it ever comes to that, though I can't see needing it unless I'm outside the car when it's in my hand.
I bought the training tape too, but there was some discussion about ASP's technique in the practical tactical forum. Do a search for more info.
Airweight is aluminum. It's lighter to carry, but may bend when you hit something hard.
Chrome is actually black chromed steel, the standard finish.
Electroless Nickel is the non-corrosive finish for marine environments. It's a dull silver color.
I forgot what federal is.
