As leverite pointed out, the main difference between the 40 and and 45 is the bullet diameter (one is .40" and one .45"). The 45 bullets are also heavier, from 185 - 230 grains, compared to 135-180 grains in the 40.

I don't know if I would say the 45 is "better" than the 40, but it has been around about 80 years longer.

I also have a S&W SW40VE, mine has been perfectly reliable for at least 5 years, and yes it has a long, heavy trigger pull.

I only have two 40 pistols, the S&W and a Kahr K-40. The K-40 has a great trigger and is much smaller, but also cost a good bit more than the S&W.

The folks at the S&W forum say this is the place to have the Sigma Trigger fixed. http://www.lsgmfg.com/index.htm They say it is even free-done under S&W warranty.
