I bought a Smith and Wesson SW40F at Walmart for that purpose for less than $50. It's a semi automatic on a 45 ACP frame that shoots a 6mm plastic air soft pellet at 300+fps. It is powered by a gas cartridge and fires 35 times as fast as you can pull lthe trigger. Cats, dogs, sqirrels, rats, etc., just hate it. At close range it leaves quite a whelp, but will not break the skin or your windows. It's only accurate up to about 30 feet although it will shoot up to 100ft. You won't hit on every shot but heck, you've got 35 chances.
I am fortunate to have a great job that feeds my family well, but music feeds my soul.
Wow sounds like a decent buy, but its not for me. Im looking for a rifle with pump action under 500 fps...............the laws here are around how the "weapon" functions and at what rate. I know which i want ............Just have to find a way of getting it Heh
