Id really really rethink the whole Sigma thing 1st of all....there are a bunch of better options at or very close to the price of a sigma, if you've got $300 or so to spend on a sigma, save a little more and get a used Glock.....as far as 9 or 40...for various reasons and to be short, 9mm.
I disagree, the sigma is a good gun for the price and the fact is that some people do not have more than a set amount to spend, I hear all the time spend a little more and get a glock, there is nothing wrong with S&W , to many people act like glock is the only gun on earth and that is wrong, and used guns are not cheap also. I would rather spend $259.00 for a NEW sigma at academy sports and have money left to buy a holster and some ammo rather than spend $400.00 on a USED glock. no offence HUNNG, rant over.
