The Striker is a variation of the Supersport, a Lightning, although the Striker has a 1/2" screw cut barrel.
I find both the Supersport and Lightning just about the harshest springers I've ever used, although a few of them have not been too bad.
My own Supersport was extremely harsh, probably worse than most, but after a bit of work I've managed to tame it. It's still probably the harshest springer in my collection, but there's always been something about it that appeals to me.

Far too many rifles & pistols to mention here.
