I had the same dilemma. I ended up paying the extra money for the M&P. I've since gone to the range and tried the sigma. I'm very happy with the choice I've made. The M&P feels more solid. To me it's just an all around better gun.

i got a sigma 40 for christmas, i didnt like the feel of the hard , not smooth trigger.

called the S&W warrenty center to see if they had any advice on a trigger mod that wouldnt void the warrenty.

they told me they they could do it under warrenty (no cost or shipping) and bring the trigger down from a 10lb to a 6-7 lb trigger and made it a lot smoother and lighter,.......i love it since then.

look on the back of your S&W warrenty brochure and find the texas center , call frank smith he really took care of me and the sigma and had it back to me within a week...

It would depend on if you want a self defense or target gun. My neighbor has an M&P 9c and I a Sigma 9VE and we always shoot each others guns. His trigger is much lighter but I still shoot my Sigma as well as the M&P. I guess it's what you're used to. For every day carry I'll take the Sigma hands down. The M&P's trigger is too light for comfort without a safety for my liking. The Sigma is a SHTF gun and nobody will be noticing the 10# trigger at that time.

I shoot a M&P 40 and a Sigma 40 and the M&P wins hands down in my book.
I put a Pachmayr "slip on " grip on the Sigma and for some reason it shoots a lot better now even with the shity trigger.

i know t7-his isnt exactly what was asked and it may be a trigger thing but my sigma has a lightened trigger but i shot alternated shooting one day between an xd 40 and my sigma 9 and was able to hold a 6-7in group with the sigma and was able to hold 4-5 in group with the xd (from 10yards) . and about the trigger where the xd is simply click feeling the sigma is pull click. i mention this because i imagine the xd and m&p are similiar as far as accuracy is concerned. im not an experienced shooter by any means nor am i really familiar with either gun, and this was shooting the best i could freestanding

That's the key. you bring that pull down some and all of a sudden the Sigma has no trouble keeping up with a lot of other higher priced weapons. Even without it you can get used to it but it really is like another weapon if you can get some of that huge pull worked out. I still say the Sigma is one of the more underrated weapons out there.

I'm going with the M&P, based on feel
