Very few handguns emulating well known firearms have much accuracy, they sell mostly on looks.
The pump ups do have good accuracy, even Crossmans and particularly Benjamins.
I still wage war on the tree rats with my Benjamin Limited edition 392 I have had for 7 years now. I have to put a new kit into it, started leaking air yesterday. I quit keeping count about 4 years ago, and had 572 notches then (actually marks on a paper I kept in my closet). I think conservatively it has dispatched at least 900 of the little furry critters.
