Google is your friend. I think this is what you are looking for:
I can't seem to find them at any local dealers, gun shows, or even online. So, how do people buy these? HELP damnit!
Where are you located?
Cheapest I've seen is $530...I seriously doubt you'll find one under $500.
Well I ain't wanting to spend a whole lot. What are other good .40 S&W pistols?
??? I'm wanting to spend around $400
You can forget about the Sig. Sigs are in the $700 range. You might be able to find a Ruger for $400. You could also consider a Smith & Wesson Sigma.
Stoeger Cougar is another option.
If money is that tight, you might want to reconsider your caliber choice. 40S&W ammo is quite a bit more expensive than 9mm ammo. Just my .02
