The Sigma competes in the affordable protection end of the market. The M&P competes well with anybody...
The M&P is one to keep an eye on. They are gaining in popularity in the ISPC shooting competitions amazingly fast. I like to look up the numbers of each brand and type that are entered in that contest every year to see what the real pros prefer to shoot. M&P is the new kid on the block and seems to be really taking off. I’ve never shot one but they gotta be impressive to increase their numbers in ISPC like they have in such a short time. Time will tell if they are “flash in the pan”.
