Yes it is used for rodent control but nothing much larger. I also recommend using Hollow point .22 pellets they make a clean kill.
See the link below for the 2240 parts diagram.
Crosman still supports this air pistol. See the link below.
None that I know of, the standard 2240 has no way of mounting a laser without some sort of modification.
Shoulder stock. Grips, Breech, Barrel, Sights, Trigger. Just about everything.
Feinwerkbau, IZH, Benjamin (Marauder), or Air Force (Talon-p). All of these are excellent, but costly ($300 and up) Or a Crosman 2240 (About $60)
If you are looking to shoot small game with a gun not a rifle then I suggest finding one that fires a .22 cal pellet not a .177 pellet. The .22 cal pellet may be slower but it has more knockdown power. Also use "hollow point pellets" or "hunting pellets" not the normal dome pellets. Look at the Benjamin HB22 or the Crosman 2240 model pistols they are both .22 cal. but take your time and look at all the different models, go to: http://www.pyramydair.com/cgi-bin/show.pl?cmd_category=show&category_id=4 What ever you do do not use a BB gun for hunting. BB's do not deform when they hit a target and will make the animal suffer, Pellets are more humane.

Several that I suggest. Benjamin EB22. It a .22 caliber single shot Pistol. Excellent quality. Crosman 2300S or 2300T. but they are expensive Crosman 2240 is more affordable Crosman 2250 with shoulder sock and scope or Walther PPK/S bb pistol. Pure fun, Feels real but not Accurate. or any of the Walther's pistols. stay away from Daisy or Marksman. I own over 70 different airguns. See the link below for airguns and read the reviews.
Benjamin model EB22. Crosman model 2240. Benjamin Marauder Air or C02 Pistol. All 3 of these are .22 cal C02 air pistols, There are several others but they are spring or pneumatic not C02 systems
There are 2000 pounds in one ton. Therefore, 2240 pounds is equal to 2240/2000 = 1.12 tons. This is talking about a US ton. A UK ton has 2,240 pounds.
