With the current Crosman-made products, the .22 392PA and the .177 397PA are traditionally called Benjamins while the same gun in .20 is a Sheridan, even if Crosman won't print those names on the guns!
Sheridans come in two flavors, plain and shiney. The Blue Streak is the black one, I guess because it looks like a traditional blued steel rifle, and the nickle-plated version is the Silver Streak.
I have a 392PA (I just call it a 392) and really like it. I mounted a pistol scope on mine, scout rifle style ahead of the rear sight. I think the guns are too hard to load and pump with a conventional rifle scope though. Most folks just use the open sights or install a Williams peep sight (sold by Crosman).
My rifle loves RWS Superdome pellets. Crosman hollow points are OK, but other Crosman pellets don't work too well in my gun. Geez, cheap Daisy wadcutters shoot better than the crosman pellets in my 392. Weird, huh?
A metal and wood rifle that's easy to shoot, no recoil or hold sensitivities to deal with, and if you like to work on your own guns you can with just simple hand tools. There are modification that can be done to increase power and/or reduce the pump effort. Mac1is famous for their "steroid" mod they do on these guns. The guns are simple enough that a lot of people (myseld included) do their own work on them. On 8 pumps mine runs about 680. I usually use 4 pumps (520fps) plinking and paper punching at 10 to 20 yards in the backyard.
I also have a 1965 model Sheridan Blue Streak. Now there is a really sweeeet rifle!

I think the Benjamin and Sheridan rifles are just great. Try it, you'll like it!
