At first, I liked the fit and feel and power.
Things I would have changed:Internals are jinky and will malfunction very quickly.
What others should know:For cheap plinking it's ok. Not for serious shooting. Plastic is cheaply put together with weak screws.

Where can you get spare magazines for it
Does this gun curve bbs? Should I use crosman copperhead bbs for this gun?
Any brand BB's will work.

Fits my hand well, larger grip than sorry me of my others. I like the little bb magazines, they work in my wife's umarex as well, so we share.
Things I would have changed:The little black plastic piece on top popped right off mine when I got it out of the package. When I tried to put it back on, I somehow or other got the internals boogered up. Ended up having to take it completely apart twice before I found a diagram of the crosman c11 (same guts, different package) and got it back together right. I'm not sure why that piece has to be detachable. I epoxied it back in place, so it shouldn't go anywhere on its own .
What others should know:I'm a classic guy, Crosman and Daisy all the way. I usually like my crosmans a little better than daisy, but this one isn't up to par with my 1322, and definitely not with my old 101. It's fun to play tin can massacre with, but not much more. Makes a decent companion gun to my 1077 rifle. For a little more, the daisy 5501 is a much better gun.
