It all comes down to what fits YOU and nothing else. Glocks are a fine firearm but they don't fit ME. M&P's fit very well and mine have proven themselves many times over. My Full Size .40 has over 15,000 rounds downrange in USPSA/IDPA matches and has never missed a beat.

Many of my fellow competitors have switched from Glock to the M&P simply due to fit as well.

I am not bashing Glock's by any means...the optimum performance always seems to come from having a good fit.
