I can apreciate cash being a real issue but recommend that you buy what you want and don't worry about the cash so much. If you don't you'll kick yourself later. I find that in those few instances where I settle because of cash constraints, I kept looking at what I want while kept not wanting what I have more and more.
If you don't have the funds, I say wait and save up until you do then get what you really want.
In the long scheme of things, your cost in ammo (9 or 40 or 357 or 45... you get the idea) will out do the cost of the gun in the first place.
Check out CDNN at (

Lastly, take my advice with a grain of salt. I mean I do settle when it is really NOT feasable not to. I mean I drive a Ford even though I dream of the Porsche.
