I love practicing with airguns; cheap, quiet, no range fees.
The crosman you selected is very accurate, with decent pellets (brown box crossman premiers) it will group at .5" or better at 10 yards or so.
I own the crosman and the Baikal IZH-46 Mr. Borland showed.....the IZH will have you wanting to replace most of the triggers on your firearms to try and match it....its that clean, crisp and light. With a 2x scope on mine its a 10 yard bug hole every time. A bit pricey for an air-gun, but worth every cent.
The crosman is a very accurate pistol, with a very heavy trigger (mine breaks at around 5 lbs). Great little air-gun for hunting small game.
You wont be disappointed with it for the price.
